Blogs and Media | DieselNet What is a blog and who speaks of the Blogs? Blogs or weblogs are not citizen journalism as generally described, some studies indicate that these online consumer assistance program editions, although consumer assistance program spread over the network, can not be considered as journalism, because neither have a large scale audience, have no influence on the opinion public consumer assistance program or political, social or cultural life. Blogs are just the result of the evolution of the Internet. The mainstream media have joined to their pages, consumer assistance program have adopted them as their children seeing them characteristics of boldness and curiosity of children, but no more than that. Some media used them to extend their expansionism basing them as means to free advertising, see the example in "THAT" between otos European media. Others incorporate them as a tendency to novelty and innovation. yes one thing is certainly true, there are blogs and every day we hear of them as a new form of expression, varied, consistent and ambitious.

The oil from Iraq to BP, Shell and Exxon | DieselNet After four years after the American invasion of Iraq, American companies in Britain and much of the oil wealth of the Arab country will be - considered the third largest reserves in importance in the world Oil companies of the two countries by their military forces invaded the Arab country in 2003, Iraq's oil wealth will be if a new law to be presented to Parliament shortly Baghdad remembers. So says today's Sunday "The Independent of Sunday", which has seen a draft of that law, whose production has been directly involved, ase certification practice test the newspaper said, the United States Government. The law in question gives big oil companies like BP, Shell and Exxon thirty-year contracts to extract Iraqi crude force and allow the first large-scale operation of Western interests since the industry was nationalized in 1972. Executives and industry analysts say the law, which would allow companies ase certification practice test from both countries to pocket ase certification practice test up to 75 percent of the benefits in the early years, is the only way for the Arab country to put back up its oil industry after years of sanctions and war. However, the British Sunday explains, the law provides for production sharing agreements, something very unusual in the Middle East: well, the oil industry of the two largest producers - Saudi Arabia and Iran - is under state control. Critics of the new legislation censor ase certification practice test concerned to compel Iraq, whose economy depends 70 percent on oil, to make delivery of its sovereignty to "unacceptable levels". At the same time remember that when in 2003, British Prime Minister Tony Blair justified the invasion of Iraq in Parliament, described as "false" allegations that Washington and London only wanted to take the oil from that country. Also former Secretary of State Colin Powell said at the time that "the oil of the Iraqi people belongs to the Iraqi people, it is their wealth and used for their benefit." According to supporters of the new legislation, the clause by which allow Western companies with up to 75 percent of oil profits will last until they have recovered the initial ase certification practice test cost of drilling. Then they will be content with 20 percent of profits, according to industry sources in Iraq, although, as stated by "The Independent", the latter percentage is twice the normally established in such agreement.

(Notícia em Inglês) Idoia Field Aranguren investigated in his dissertation the use of heterogeneous catalysts for synthesizing biodiesel, a biofuel similar to those of petroleum diesel fuel characteristics, but with the advantage of being renewable. Facing homogeneous type catalysts, has worked in the development of heterogeneous catalysts "that can recover and reuse the catalyst and greatly reduce the environmental impact." The synthesis of biodiesel is based on a reaction known as transesterification. It's disla combining vegetable oil with a light, usually methanol alcohol. The triglycerides of the oil through a catalyst, reacts with the methanol and converted into biodiesel (more specifically, fatty acid methyl esters that are to constitute the biodiesel). "In this thesis we have established the basis for developing a heterogeneous catalyst capable to be implemented in industrial processes for production of biodiesel," says the researcher. In addition, it has identified the most influential parameters that determine the behavior of the catalyst.

Greetings smog check bakersfield ca bachelor smog check bakersfield ca embryos, we meet again in this exciting world of chemistry, the best of success for this his last year of high school. Here I am going to put two questions smog check bakersfield ca of this first period: 1 How important is the new Catalyst recently discovered smog check bakersfield ca for the manufacture of plastic bags? 1 How important smog check bakersfield ca is the new Catalyst recently discovered for the manufacture of plastic bags? A: First of all we know that is a catalyst, to know that it is important in the manufacture of bags. The catalysts are made on a ceramic structure, which is coated with a thin layer of rhodium and platinum. This structure has the form of an array of hexagonal tubes, being quite similar to a honeycomb. This form means that when the gases are being issued with a catalyst surface can act on them. The catalyst is developed to work in harmony with the power system of automobiles. The lack of this equipment smog check bakersfield ca or the use of one false causes several problems affecting the normal operation of the automobile. In industry, for many chemical reactions are possible with speed and efficiency necessary to be present intermediate molecules called smog check bakersfield ca catalysts, as they act is not always well known. smog check bakersfield ca Many reactions do not resolve spontaneously, they do so very slowly, or require very high temperatures to occur. However, they can occur almost miraculously if a third substance, which in general smog check bakersfield ca terms are called catalysts is present. In any industry that needs these changes from one product to another, catalysts which are generally metal-type compounds are used. They accelerate reactions smog check bakersfield ca at temperatures that are compatible with the industrial process. The process is very similar to what so often happens inside living cells. There a huge amount of necessary smog check bakersfield ca to sustain life, that the pH and temperature of the cell must occur reactions were performed. Moreover, if it were not for the fact that the chemical normally used to palladium smog check bakersfield ca as a reagent for polyethylene, smog check bakersfield ca plastic bags would be very poor, as they break with a load of just a couple of blocks and a carton of milk . However, thanks to the efficient work of the precious metal, we do not suffer this problem. Converts palladium acetylene to ethylene, which is used to make polyethylene. Ethylene always smog check bakersfield ca contains traces of acetylene, because both substances are derived from crude oil and is not easy to separate. However, the acetylene conversion interferes ethylene to polyethylene. Therefore, unless it is first converted to ethylene by joining two hydrogen atoms in the presence of palladium, the resulting plastic is poor. World production of polyethylene smog check bakersfield ca is 80 million tons per year, so the acetylene conversion costs are considerable. These costs could be significantly reduced by replacing palladium with cheaper but just as efficient materials. A team of scientists from the Max Planck Institute for Chemical smog check bakersfield ca Physics smog check bakersfield ca of Solids in Dresden, the Fritz Haber Institute of the Max Planck Society in Berlin and other German institutions has developed a catalyst smog check bakersfield ca using iron and aluminum which makes an equally good job on the conventional palladium catalyst, smog check bakersfield ca but obviously costs much less. Yuliannys Esquea # 13 October 31, 2012, 8:46 am 2 What's true that now may take acetylsalicylic acid in gaseous form? R: Aspirin is widely used as an analgesic (pain reliever) and antipyretic (fever-reducing). It is also used to help prevent heart attacks, strokes and blood clots in people at risk of developing smog check bakersfield ca blood clots. Aspirin (acetylsalicylic acid) is an aromatic compound containing smog check bakersfield ca both a carboxylic acid functional smog check bakersfield ca group and an ester functional group. Aspirin is only slightly soluble in water and acid solutions as present in the stomach. smog check bakersfield ca Aspirin containing polar functional groups which can form hydrogen bonds with the polar water molecules. Aspirin is soluble in basic (alkaline) solution, so that it is easily dissolved in the duodenum, which is the first part of the intestine. Aspirin ionic salts such as sodium acetylsalicylate, are more soluble in water, and which form strong ion-dipole smog check bakersfield ca interactions with water. Yuliannys Esquea # 13 October 31, 2012, 16:27 1 How important is the new Catalyst recently discovered for the manufacture smog check bakersfield ca of plastic bags? R: Catalysts
Rafael Luque, professor of inorganic chemistry at the University of Córdoba and Rick Arneil my kids ggusd Aracon graduate of Xavier University in Cagallan de Oro (Philippines), have developed a new way of producing my kids ggusd cleaner and cheaper biodiesel from waste after been known at the social network for scientists ResearchGate.Los my kids ggusd 2.0 results of joint work have been published in the journal Green Chemistry. According to Luque, who have established the process for producing my kids ggusd biodiesel is based on heterogeneous catalysis. "We have achieved a transesterification (triglycerides) and esterification (fatty acids) for the simultaneous production of fatty acid methyl esters (biodiesel), achieving my kids ggusd a cleaner and biofuel from waste frying oils," said Luque Sync platform . "In addition, the carbonaceous material used as catalyst is derived from corn cobs, another widespread food residue in the Philippines," he adds. Luque explains Rafael my kids ggusd catalysis have developed has numerous advantages my kids ggusd over conventional my kids ggusd methods using sodium or potassium hydroxide as a homogeneous catalyst, especially when waste oils are used with high fatty acid content (10%). In addition, he notes, the catalyst is recoverable and reusable in the process. "This is a cheap material compatible with the environment to be derived from biomass, and we have seen that it could also have other applications such as chromatography and even to trap CO 2 absorption." my kids ggusd I really like the idea that society begins to produce cleaner and environmentally friendly products such as biodiesel, and q gives us exactly the same performance as any other fuel but even more important that cost much less and producing less CO2 . But more complicated is that the oil companies no longer produce oil making biofuels not develop properly because the oil continues to lead the industry in fuel. Norman S. Tapia Delete Reply Generate Biodiesel has been one of the innovative my kids ggusd ideas of the last time, however the existence of normal oil remains the market leader. Biodiesel has been a major innovation, since this is an organic fuel from the heterogeneous catalysis of triglycerides and fatty acids, in addition, the subject deviates at the point you say get the oil biodiesel waste frying, since nowadays, most of the fast food restaurants work with this and that could bring consequences when ingested, however, continuing with the theme, the oil industry will not allow this fuel to win the market, and production will continue to date. However proeycta future is the massive use of the fuel, since it is cheap and compatible my kids ggusd with the environment, ie, not at all like dania oil. Nataly Saa.

Security in the XXI Century * As a result of this investigation a paper submitted for publication clear smog Fuel Processing Technology, in which participated postdoctoral fellow, IIM investigator clear smog Heriberto Pfeiffer and student Nicholas Santiago Torres emerged Claudette issis Romero Ibarra, postdoctoral fellow of the Institute clear smog of Materials Research (IIM), clear smog UNAM, won the scholarship L'ORÉAL-UNESCO-Mexican Academy of Sciences (AMC), with which it intends to continue its research into biofuels clear smog using a high performance heterogeneous system. His work represents a significant difference from other studies using homogeneous catalysts, because the heterogeneous reduce costs and simplify the process to facilitate the separation and purification of the resulting products: biodiesel and glycerol. Furthermore, the latter can produce other value added services. While working in the Lab E 101 Gas Absorption, by Heriberto Pfeiffer Perea (of that university entity), the graduate of the Faculty of Chemistry referred what it means to have fellowship and applications that want to develop. Although I never thought I could win this award, noted that the last two years he has devoted to the project for biofuels based on sustainable materials clear smog that fold down high levels of pollution and global warming effects. He also thanked the largest opening in the exact, chemistry clear smog and physical science in the country where participation of women gaining more ground. "Mexico depends on oil. Find alternatives is an option clear smog that provides, at the same time, environmental and economic aspects. We must reduce pollutants clear smog generated by burning energy and develop new routes of synthesis clear smog of chemical products derived from it, "said Issis. Capturing clear smog carbon dioxide production of biodiesel Al mentioning the project led by Pfeiffer explained clear smog that capture carbon dioxide (one of the gases that contributes to the greenhouse effect) in different clear smog ways. This is generated from the combustion of oil, industrial plants, burning coal or wood to produce electricity and using motor vehicles. Ceramic materials for this application as lithium silicate and / or sodium zeolites, layered hydroxides and zirconate, with particular attention to the sodium zirconate synthesized. "The project that won the scholarship, develops, synthesized, characterized and evaluated catalytically new ceramic materials, ie, we study how these materials work for the production of biodiesel." For this, a chemical reaction between the ceramic (catalyst), different types of oils and methanol, which lead to the obtaining of combustion is performed. "The reaction to produce a biofuel or biodiesel is called transesterification reaction, ie transform triglycerides, fatty acids or oils in different esters. For this, the oils with an alcohol is methanol or mixed in the presence of a catalyst and methyl esters produced (chemical name for biodiesel), which has many advantages over other types of energy. " Advantages Biodiesel is an alternative fuel and sustainable energy and has advantages over oil: it is not toxic, renewable and produces clear smog no sulfur oxides, detached from the combustion of gasoline, produce acid rain. Another advantage is its biodegradability. Take part in the carbon cycle, that is, the same carbon dioxide that comes from burning is absorbed by plants and converted into oils used to produce it again. Its implementation is efficient since it does not need to modify the engines clear smog of motor transport, as it is possible to combine it with the conventional rate of up to 20 percent biodiesel. Traditionally to manufacture with homogeneous catalysts, sodium hydroxide and potassium hydroxide, which hinder the purification of final products is used. In the proposed system using the heterogeneous solid phase ceramic as sodium zirconate and vegetable oils. As a result of this research area have
In the transesterification reaction of an oil to yield biodiesel, homogeneous catalysts are used, such as caustic, potassium hydroxide or sodium methoxide. These catalysts have a number of disadvantages: However, the use of a heterogeneous catalyst solves these problems can be easily separated from the product, can be regenerated and reused, and can operate a continuous processworks process. Companies like Repsol processworks have delved into a study whose goal is the analysis of a production process of biodiesel using heterogeneous catalysis, obtaining a suitable solid catalyst (catalytic core), and the study of their properties and catalytic activity. And of course in the economic section of the process optimization and evaluation of its performance relative to the process with homogeneous catalyst. This news is very interesting. Indeed the catalyst used in the synthesis of biodiesel is sodium or potassium methoxide (methanol with sodium hydroxide or potassium hydroxide dissolved). The possibility of using heterogeneous catalysis is a revolution. A evil. Have ye noticed that the methanol used to make biodiesel is obtained from natural gas or coal ?. While that alcohol is not biomass for biodiesel biodiesel is not really. December 6, 2007, 19:54 I announce that in addition to the entries that do to the blog, the evaluation will consider the comments that you do to other groups. It is important that we create a learning community, helping one another. December 6, 2007, 20:40 I leave the address of a wiki you can find the best tips to make the presentation of your work http://sirfreakthemighty.wikidot.com/tips:presentacion December 8, 2007, 19:42 It seems perfect Augustine. I've been pretty busy these days, but even so, I've been watching what you commented me on Monday about what biodiesel and the web and have a good solution. I found two very interesting programs to teach on Monday. It took me more because processworks I have not seen in years php but I've finally made it work. As for the programs / tools: One is a Wiki itself, is the "mediawiki", is the same engine that wikipedia GPL. http://es.wikipedia.org/wiki/MediaWiki The other is a very interesting tool that looks a lot like the tool that the university gives the link www.uhu.es/sa but much fuller in my view is egroupware, plus everything in it also carries with it a kind of blog that you can complete with many options. http://www.egroupware.org/ This is very interesting because it is based on the new trends processworks of the Web's called 2.0 and it seems quite functional for what we want to develop. Greetings processworks December 8, 2007, 22:23 Fran, you are not liking me how nothing is running our wiki. The site offers very few possibilities in improving the appearance of eyelashes. I've seen yours and I find it very interesting (with the same style as the wikipedia). How I can do the same? A greeting !! December 9, 2007 16:16 Well I'm thinking continue using PBwiki as yourself processworks you say, da few job options, processworks as it is very limited and if you want that is not limited you have to pay $ 10 / month minimum and there hosting where host a website a year much less, about 40/50 per year or even less, and you have many more advantages of using using the "mediawiki" that I referred to earlier. December 9, 2007, 22:08 I do not mean that. I say how do I put my wiki pages as are those of Wikipdia or yours. At the top of each page there is a box with links to different heights of the page (a link for each title). Is that how? We contact by mail or talk to you tomorrow! December 9, 2007, 22:28 Hi I'm Carolina I love the idea of the wiki and I have proposed to my coworkers and we are interested in nosotroas hacelo tb but please I need you to tell me as I can have hacela junior suit. my blog is the Q04.ecribirme alli.Gracias December 10, 2007 2:37 Hi, I think the wiki is much to be gained if, for example, enfocáis as a tool to create the final text of your group. I like the page that have what is called biodiesel? , Could be part of the final text. You only have to give the button to the bottom of the wiki so that you print it as pdf December 12, 2007, 19:24 I've tried to create a PDF, but goes something processworks like "amorphous" without a clear structure, but rather appears to be a tool that is still not very refined within the wiki. December 13, 2007, 10:55 AM Hello everyone. I tell you that your need to promote the link from another group. This is the
IEO | Science | Network | Training | Contact | Home | Opinion | Features | News | Interviews | Multimedia A Spanish and Filipino innovate in the production of biodiesel through the network ResearchGate Rafael Luque, a researcher the marlborough at the University of Córdoba, and Rick Arneil Arancon, university graduate in the Philippines have jointly developed a new way of producing cleaner and cheaper biodiesel. The system obtains high quality fuel from plant waste frying oils, using a carbonaceous catalyst waste material from corn cobs. All this thanks to the communication established in the social network for scientists ResearchGate. SINC - If there were no ResearchGate, Rafael Luque, professor of inorganic chemistry at the University of Córdoba and Rick Arneil Aracon graduate of Xavier University in Cagallan the marlborough de Oro (Philippines), hardly have known. But thanks to the communication established with 2.0 social network for scientists, both have developed a new way of producing cleaner and cheaper biodiesel from waste. Arancon was doing his job in 2010 Masters race weekend when contacted on ResearchGate with Luque, an expert on biofuel catalysis, nanomaterials and nanoparticles supported. "He was doing a project the marlborough on biodiesel and collaborated initially only sending literature the marlborough and supervision, then guidance on how to approach the project. And finally, I sent their samples from the Philippines for me to do the test and characterize in the laboratory of my university, "Luque explains to SINC. The results of joint work have been published in the journal Green Chemistry. According to Luque, who have established the process for producing biodiesel is based on heterogeneous catalysis. "We have achieved a transesterification (triglycerides) and esterification (fatty acids) for the simultaneous production of fatty acid methyl esters (biodiesel), achieving a cleaner and biofuel from waste frying oils. In addition, the carbonaceous material used as catalyst is derived from corn cobs, another widespread food residue in the Philippines. " Luque explains Rafael catalysis have developed has numerous advantages over conventional methods using sodium or potassium hydroxide as a homogeneous catalyst, especially when waste oils are used with high fatty acid content (10%). the marlborough "The conventional process results in the formation of soaps and emulsions such oily residues, whereas our procedure simultaneous transesterification and esterification is achieved, avoiding cumbersome processes of separation and purification of biodiesel obtained" he explains. In addition, he notes, the catalyst is recoverable and reusable in the process. "This is a cheap and environmentally the marlborough compatible material to be derived the marlborough from biomass, and we have seen that it could also have other applications such as adsorption chromatography and even to trap CO2. Rick Arneil the marlborough Arancon SINC that the collaboration established with the Spanish researcher through ReseachGate has been central to his work. "It's the marlborough one of the most respected in the field of biofuels the marlborough in Spain and Europe experts. Besides guiding me throughout the process, he has made all the materials characterization of my project and I've taken care of the synthesis. Without the means of his laboratory, never would have known if my idea could have been put into practice. " According to Rafael Luque, ResearchGate is a powerful tool to foster collaboration the marlborough between scientists platform. Luque highlights the opportunities through this network for researchers who live in disadvantaged to be able to establish collaborations with researchers who have more open countries media. Luque is now collaborating with another Filipina young researcher is doing a project for biodiesel from cultures of a type of algae called spirulina. Their meeting point was also ResearchGate.

Industrial catalysts are divided into two main types - heterogeneous, where the catalyst is in a different phase from the reactants, and uniform, in which the catalyst and reagents are in the same phase. Researchers from the Department of Energy (DOE) 's Lawrence Berkeley National Laboratory (Berkeley Lab) have combined the best features of both types of industrial catalysts by encapsulating nanoclusters of a heterogeneous metal catalyst in the branched arms of molecules known as dendrimers. The results homogeneous nanocatalysts that are sustainable and have a high reactivity and selectivity heterogenizados. In addition, these homogeneous nanocrystals heterogenizados promise for bridging the gap between industrial catalysts, which carry out simple reactions, and a third type of catalyst, the proteins known as enzymes that nature uses to perform complex biochemical reactions. Catalysts are used to initiate virtually every industrial manufacturing process that involves chemistry. Metal catalysts proconve have been the traditional battle horse, but in recent years the nano-catalysts have increased in importance. "From our work, it has become increasingly clear that, at the molecular level, all heterogeneous catalysts - enzymes and homogeneous - work the same way," says Somorjai. "We have now shown that working proconve with metal nanoclusters, the same chemical that can be done with homogeneous or heterogeneous catalysts." the purpose is genar networks catalysts that are capable proconve of complex reactions. The key to the success of the latter investigation was encapsulating metal nanoparticles within dendrimers. Somorjai, Toste and co-authors used gold nanoclusters and polyamidoamine (PAMAM), a common proconve class of dendrimers suitable for numerous applications in materials proconve and biotechnology. Successfully proconve tested the dendrimer-encapsulated catalyst cyclopropane, a biomolecule widely used in the pharmaceutical and chemical industries, and typically formed via homogeneous catalysis. Since flow systems are widely used in industrial chemistry, the concept of replacing homogeneous catalysts with dendrimer-encapsulated proconve heterogeneous catalysts whose product selectivity can be controlled should be a popular alternative. proconve "Highly selective catalysts, especially those that can be easily recycled, are vital to the development of sustainable chemical processes," says Gross. "In the future, our technique proconve should be possible to combine heterogeneous and homogeneous catalysts for specific product with very high selectivity."

A catalyst emissions testing tucson is a chemical, simple emissions testing tucson or compound substance which modifies the rate of a chemical emissions testing tucson reaction, but without intervening in it becoming part of the products resulting therefrom. The catalysts were characterized emissions testing tucson according to the two main variables that define them with: the active phase and selectivity. The activity and selectivity, and even the very life of the catalyst depends directly on the active phase used, so two major subgroups emissions testing tucson are distinguished: the elements and compounds with conductors and electronic properties of the compounds lacking free electrons and are therefore, insulation or dielectric. Most solid catalysts are metals or oxides, sulfides and halides of metallic elements and semimetal elements such as boron aluminum, and A catalyst support as catalyst in solution emissions testing tucson with the reagents, or in the same phase as they are called homogeneous catalyst. The catalyst is combined with one of the reactants to form an intermediate compound which reacts with the other more easily. However, the catalyst does not influence the equilibrium of the reaction, because the decomposition products in the reactants is accelerated to a similar degree. An example of homogeneous catalysis is the formation of sulfur trioxide by reacting sulfur dioxide with oxygen, and using nitric oxide as a catalyst. The reaction intermediate compound momentarily form nitrogen dioxide, which then reacts with oxygen to form sulfur dioxide. emissions testing tucson Both the beginning emissions testing tucson and the end of the reaction the same amount of nitric oxide. A catalyst that is in a different phase from the reactants are known as heterogeneous catalyst or contact. Catalysts are materials contact capable of adsorbing molecules of gases or liquids on their surfaces an example of heterogeneous catalyst is finely divided platinum to catalyze the reaction of carbon monoxide with oxygen to form carbon dioxide. This reaction is coupled catalysts used in automobiles to remove carbon monoxide from the exhaust gases. There are certain substances called promoters, which have no catalytic activity itself, but increase the efficiency of the catalysts. For example, adding alumina finely divided iron, this increases the capacity of iron to catalyze the production of ammonia from a mixture of nitrogen and hydrogen. Moreover, the materials which reduce the efficiency of a catalyst are known poisons. Lead compounds reduce emissions testing tucson the ability of platinum to catalyze; therefore, a car equipped with a catalyst for emission control requires unleaded gasoline. The most usual metal catalysts are able to produce reversible chemisorption reactions, as in the case of nickel, palladium, platinum and silver. Among the catalysts based on metal oxides are distinguished stoichiometric oxides and oxides that gain or lose oxygen from the surface. The most prominent by its catalytic nature sulphides emissions testing tucson are metal salts which are used in sulfur removal processes, and chlorides, which are catalysts for oxychlorination emissions testing tucson processes. The catalysts called "bifunctional" are both in the support phase and supported emissions testing tucson catalysts of different elementary steps of the chemical reaction, different catalytic following schemes. They are primarily used in the reforming of gasoline. Awesome Inc. template .. Template images by graphixel. Powered by Blogger. emissions testing tucson
Catalytic oxidation generates hydrogen from clean water and sunlight Posted by Julio Cesar on Mar 12th, 2010 and filed under trends. You can follow any responses to this entry through the RSS 2.0. You can leave a response or trackback to this entry Chemists california emissions at Emory University have developed the most potent homogeneous catalyst known, that for the oxidation of water being considered california emissions an essential component for generating hydrogen fuel from water using only sunlight. The research team says that to be a viable option, the water oxidation catalyst (WOC) must have selectivity, stability and speed. New research aims to mimic natural processes as photosynthesis to generate clean fuel, with the long term goal of generating hydrogen from water using only sunlight. The hydrogen becomes the fuel burns with the byproduct water, flowing back into the clean and renewable cycle. The three major technical challenges involved in the process are the development of a light collector, a catalyst to oxidize water to oxygen california emissions and a catalyst to reduce water to hydrogen. The research team has doubled the complex natural process of photosynthesis using the synthetic, carbon-free, homogeneous system with a cobalt-based WOC.

Treatment of phenol-contaminated water by heterogeneous Fenton process Concern for the development check engine code for the treatment of industrial wastewater has grown significantly in recent years. Phenol has been established as the model compound for evaluating proposals for new treatment processes. The Fenton heterogeneous process presents the advantages of the conventional Fenton process or homogeneous, but causes less contamination check engine code of the effluent with iron used as catalyst. Effective purification of industrial wastewater has become an increasing concern in recent decades. check engine code The legislation of developed countries, and increasingly in developing countries, has evolved to reflect this concern and environmental regulations leading to increasingly stringent standards. Industrial effluents containing toxic pollutants and often resistant to conventional wastewater treatment, so there is the need to develop effective technologies for removing pollutants and effort in research and development has deepened. Phenol and phenolic compounds are raw materials or intermediates in numerous petrochemical, chemical and pharmaceutical industries, check engine code and are likewise oxidative degradation products of aromatic hydrocarbons of higher molecular weight. Therefore phenol check engine code is possibly the most widely used compound for the development of new processes for water purification model. The oxidation of contaminants in water by wet oxidation (wet air oxidation, check engine code WAO) and by catalytic wet oxidation (catalytic wet air oxidation, check engine code CWAO) using air and pure oxygen is one of the most studied technologies for removing phenols. Allows very high removal efficiencies, but requires the use of pressure and high temperature (20-200 bar, 200-320ºC), which increases the treatment. An alternative to reducing the severity of the reaction conditions is the catalytic wet oxidation with hydrogen peroxide (peroxide catalytic wet oxidation, CWPO) which is different variants. Of these Fenton's reagent is one of the leading options. In this process hydrogen peroxide is decomposed catalytically in the presence of ferrous ion to produce hydroxyl radicals which has great oxidation capacity. Application of Fenton process to the treatment of wastewater has attracted great interest due to the low cost of ferrous salts, its low toxicity and hydrogen peroxide is easy to handle and the excess is broken down into harmless products. Also, the equipment requirements are low and the reaction conditions are mild. However, the Fenton process has some drawbacks such as the high consumption of hydrogen peroxide and the need to remove the added iron, which adds additional processing steps and increases the cost. Some of the drawbacks of Fenton process check engine code can be avoided by use of a heterogeneous catalyst (heterogeneous Fenton process). The active phase is formed check engine code by transition metals, although it is usually iron, supported on active carbon, alumina, silica, mesoporous molecular sieves, zeolites, pillared check engine code clays and ion exchange resins. The major drawbacks of the heterogeneous check engine code Fenton process are derived from the leaching of the active phase when the medium pH is reduced to values of about 3, which is indeed the optimum operating homogeneous Fenton process. The catalysts supported on activated carbon can be performed by treatment with a limited leaching of the active phase. Figure 1 shows how a model waste water with 100 mg / L of phenol can be treated by a process based on heterogeneous Fenton iron catalyst supported on carbon (Fe / AC) active until the complete removal of contaminating starting. Though check engine code the disappearance of the phenol initially contained, the water is not completely decontaminated, since after treatment persist certain degradation products, mainly organic acids and their elimination is complex. Figure 2 shows the typical distribution of the organic acids formed by Fenton heterogeneous phenol treatment. check engine code The products formed in the oxidation are important when evaluating the process, with some of them, such as quinone, may be even more toxic than the starting phenol, but as shown in Figure 3 can be aromatics eliminated by applying an appropriate treatment time.

Organic diesel particle filter catalyst for the production of biodiesel Biodiesel derived from animals, used or waste vegetable oils or presented as an alternative to fossil fuels due to its renewable nature and its lower environmental impact. The current biodiesel manufacturing process is made by transesterification of animal with light alcohols (methanol) using a catalyst for the conversion (Figure 1) or vegetable oils: The catalysts used in the process are required for the transesterification reaction diesel particle filter occurs and it is possible to achieve high speed in the production of biodiesel. Conventional catalysts used industrially, are usually strong acids or bases (sulfuric acid, KOH, NaOH), allowing high conversion of biodiesel under moderate operating conditions diesel particle filter (50-70C). The catalysts are used dissolved (homogeneous catalysts) in the reaction mixture + alcohol oil making can not be recovered after completion of the transesterification reaction. This makes that, after reaction, have to be neutralized diesel particle filter and separated from the biodiesel phase with consequent environmental problems and corrosion of the facilities that are derived from the management of large amounts of strongly basic solutions (acidic) required in homogeneous process. To improve efficiency in the production of biodiesel, it is trying to replace the conventional homogeneous catalysts by solid catalysts that allow their separation by filtration of the reaction mixture for reuse. In this sense we have conducted research to develop products based on solid acidic or basic (exchanged zeolites, Nafion, CaO, MgO, ...) catalysts but still distant results to those achieved with conventional acidic or basic homogeneous catalysts. In the development of new heterogeneous catalysts for biodiesel production has recently reported the catalytic activity exhibiting interesting carbonaceous solids from the incomplete carbonization of natural organic materials (saccharides, cellulose, ...). In this line of action, researchers at the University of Whan (China) have developed diesel particle filter new catalysts for the production of biodiesel based on carbonaceous solids formed from shells of crustaceans. In developing diesel particle filter these catalysts researchers have partially carbonized transforming crustacean shells chitin, the main component of the shell in an open porous structure formed by functionalized polymers. Treatment of this material with an inorganic solid form KF basic character with interesting catalytic properties for the transesterification of oils in the production of biodiesel. In laboratory tests, these new catalysts have achieved promising results in the production of biodiesel (90% conversion diesel particle filter in 3 hours in the transesterification of rapeseed oil at 65 C + methanol). Although catalysts have some stability problems that must be solved in future developments, the benefits of this change in technology could be important catalysts for biodiesel production in a more efficient and environmentally friendly than that achieved in Today the industrial systems using homogeneous catalysts.

An example of the heterogeneous catalyst is finely divided platinum catalyzes the reaction of carbon monoxide with oxygen to form carbon dioxide. This reaction is coupled catalysts used in automobiles to remove carbon monoxide from the exhaust gases. Car catalyst: roosevelt towers the catalyst is a scrubber element exhaust. Its operation is based on metal-containing (especially roosevelt towers platinum and rhodium in very small amounts) roosevelt towers to facilitate the reaction between the exhaust gases and the oxygen of the air, to become less harmful substances. The oxidation catalysts called get carbon monoxide roosevelt towers CO is generated during combustion will become carbon dioxide CO2 to make oxygen (the first is a toxic gas and the second not), and also burning hydrocarbons (incredibly , part of the fuel entering the cylinders goes intact) causing a combustion reaction in which CO2 and water vapor follows. There are also three-way catalysts, in addition to oxidize (add oxygen) can be reduced (to remove oxygen) roosevelt towers certain exhaust. Thus, the nitrogen monoxide NO and NO2 dioxide become oxygen O2 and nitrogen N2. The normal operating temperature of a catalyst is about 800 C, and can not run on leaded petrol, roosevelt towers as this metal is deposited on the catalyst components, canceling performance.

Renewable energy, biofuels, hydrogen Chemicals Emory University have developed the most potent homogeneous catalyst known for water oxidation, considered a crucial component for generating clean hydrogen fuel using only water [...] It is also interesting: Chemists at Emory University have developed the most potent homogeneous catalyst known for water oxidation, considered a crucial component for generating clean hydrogen fuel using only water and sunlight. This breakthrough, published March 11 in the journal Science, was conducted in collaboration with the Institute of Molecular Chemistry in Paris. In the photo you can see the oxygen bubbles formed by water oxidation, catalyzed by the new tetra-cobalt diesel dpf WOC. The fastest catalyst, carbon-free molecular water oxidation to (WOC) known to date "has really raised the standard of the other known homogeneous diesel dpf WOCs" said Craig Hill, Emory inorganic chemist, whose lab led the project . To be viable, WOC needs selectivity, stability and speed. Homogeneity is also a desired feature, because diesel dpf it increases the efficiency and makes it easier WOC studied and optimized. Benjamin Yin, an undergraduate laboratory Hill, is the lead author of the Science paper. Emory chemists who are co-authors include Hill, Yuri Gueletii, Jamal Musaev, Zhen Luo and Ken Hardcastle. The Department of Energy funded the work. The WOC research diesel dpf is a component of the Renewable Energy Center Emory Bio-inspired, which aims to mimic natural processes as photosynthesis to generate clean fuel. The next step is to incorporate the WOC in a system to remove diesel dpf the water using only sunlight. The long-term goal is to use sunlight to split water into oxygen and hydrogen. Hydrogen fuel becomes. Its combustion produces water again - flowing again forming a clean, green, renewable cycle. Three main technical challenges are involved: developing a light collector, a catalyst for oxidation of water to oxygen and a catalyst to reduce water to hydrogen. The three components need improvement, but a viable diesel dpf WOC may be the most difficult scientific challenge. "We diesel dpf are looking for a WOC that is free of organic structure, because organic components will combine with oxygen and self-destruct," says Hill. Enzymes are natural catalysts. The enzyme in the evolution diesel dpf of oxygen in the center of green plants "is about the least stable catalyst in nature, and one of the most short-lived because it performs one of the hardest jobs," Hill says. "We've duplicated this complex natural process by taking some of the essential characteristics of photosynthesis and we used synthetic, carbon-free system diesel dpf and homogeneous. The result is a catalyst for the oxidation of water that is much more stable than that found in nature. " For decades, scientists have been trying to imitate Mother Nature and create diesel dpf a WOC for artificial photosynthesis. Almost all the 40 homogeneous WOC developed in labs have had significant limitations, as containing organic components that burn quickly during the water oxidation process. Two years ago, Hill's lab and collaborators developed the first prototype of a stable, homogeneous carbon-free WOC, who has also worked faster than others known at the time. The prototype, however, was based on the ruthenium, a relatively rare and expensive element. Based
Difference Between Heterogeneous and Homogeneous liqtech | Difference Between Homogeneous and heterogeneous products found all the time in our daily lives. Basically liqtech we subdivide a mixture in homogeneous and heterogeneous mixtures. Briefly, a homogeneous liqtech mixture is not easily differentiate the components thereof, while a smorgasbord can easily liqtech differentiate the various components that comprise it. An example of a homogeneous solution can be a saline solution. We can not see the different components in the solution separately as water and salt. An example of a mixed solution is a mixture of water and gasoline. These different components are shown separately. In a homogeneous mixture, the appearance is uniform, and therefore also the composition. Many of the most homogeneous mixtures are solutions. In the solution, if a component is a powder or liquid that is dissolved liqtech in the other liquid, then can not see the different components separately. We see it as a liquid. The air without any visible particles, is also smooth. liqtech But in fact the air is composed of different gases. In a heterogeneous product, we can easily distinguish different components in it. If you try to mix sand and water, it will not dissolve. So, you can easily distinguish between the sand and the water. We also have homogeneous and heterogeneous catalysts. A homogeneous liqtech catalyst is used in the same phase as the reactants and be in the same state of matter as the other reagents. Heterogeneous catalysts are used in a different phase of the reagents and may be in a different subject reactive state. The heterogeneous mixtures liqtech of components can be easily separated but separate the components of a homogenous liqtech mixture can be difficult. If you have a heterogeneous mixture of sand and water, you can allow the sand to settle and separate from other components. If you have a homogeneous liqtech mixture as a sugar solution, you must separla by the evaporation process. Other methods of physically liqtech separating the components of a mixture are filtration using a magnet, crystallization, distillation, decantation and sieving. If you have a mixture of sand and iron filings, use a magnet to separate them. Spread liqtech the mixture onto a surface and pass the magnet over it. The iron filings liqtech will start to stick to the magnet. About This Post Posted by Juliet on Apr 10th, 2011 and filed under Science. You can follow any responses to this entry through the RSS 2.0.

Neofronteras "One step closer to artificial photosynthesis - Home - A new catalyst brings us one step closer to the goal of producing hydrogen cheaply from sunlight without the mediation expensive photovoltaic cells. Light in the presence of a catalyst system southgate car centre divides the water. Source: Benjamin Yin. For decades experimenting with catalysts that will generate hydrogen from water and sunlight. The system would be very simple: in the presence of sunlight water activated by a catalyst is split, producing bubbles of hydrogen and oxygen that could be used as fuel or to produce electricity. Unfortunately, although some work does not seem to be very efficient or economical. However, with the current problems of energy crisis and climate change, southgate car centre this type of technology has received new impetus southgate car centre and begin to appear new and promising results. One of the most recent results in this regard comes from a collaboration between Emory University and the Institute of Molecular Chemistry in Paris. They have developed a new catalyst of this type (or WOC its acronym in English) that allows the production of oxygen, which would be cheaper southgate car centre and faster than other previously developed. The achievement was published in Science on 11 March. Some systems southgate car centre that were developed in the past only allow the production of hydrogen, while oxygen was combined with the catalyst destroying the process, so that after some time the production of hydrogen stopped. Above, some of these catalysts were based on expensive elements such as platinum. For a catalyze viable WOC needs to be selective, stable and fast. Furthermore, homogeneity is also desirable because it increases the efficiency and makes the catalyst easier to study and optimize. The new catalyst has all these qualities and is based on an element like cobalt is not very rare in the Earth's crust. Could potentially help the development of solar energy. The idea of this type of catalysts is copy photosynthesis, which occurs naturally in plants, to produce fuels cleanly. The next step of this research group consist of the incorporation of such a catalyst in a water photolysis system solar-powered. A long-term goal is to produce oxygen and hydrogen from water and the combination in a fuel cell would produce electricity. Hydrogen could also be used as fuel in a heat engine or for the production of other fuels. In the end there would be balance emission of greenhouse gases, again yielding water as the final product. The main technical challenges to achieve power generation system such as the development of a sunlight collector, a catalyst southgate car centre to produce oxygen WOC type (as the recently achieved) and a catalyst to produce hydrogen. The three components need improvement, southgate car centre but the WOC type catalyst is the most difficult to achieve. The goal was to achieve these researchers WOC free organic catalyst structure due to the organic components are combined with oxygen and in the process destroy southgate car centre themselves. Enzymes are natural catalysts, but natural enzymes that are part of the photosynthetic system of plants are the least stable southgate car centre of Nature and some of the shorter-lived made because of all the hard function. Craig Hill, Emory University and participant in the project, said to have doubled this natural process by copying southgate car centre the essential features from photosynthesis and using them in a free synthetic carbon system. The WOC they have done is much more stable than the corresponding native enzyme. So far, 40 have developed catalysts WOC type, but they all had serious limitations, such as containing organic components that were oxidized during the process. southgate car centre Two years ago this same group of researchers developed a homogeneous, fast and free carbon catalyst but it was based on ruthenium, a rare and expensive element. Since then experiments southgate car centre have cobalt which is much more abundant (not as much as the researchers believe) and cheaper than ruthenium. This new catalyst has proven to be even faster than the one based on ruthenium. RSS feed for comments on this post. Page generated by WordPress.
If you remember, emissions testing seattle in the first article we said ISQCH catalysis stands for Institute of Homogeneous emissions testing seattle Catalysis emissions testing seattle and Chemical Synthesis. Catalysis emissions testing seattle explain emissions testing seattle what was left for later but the differences between homogeneous and heterogeneous. Really at the Institute there is a bit of both, but traditionally it has investigated more in the first. For those who do not know something homogeneous is something that has a uniform composition and structure. Heterogeneous is the opposite. As an example I always culinary explains my friend Rachel is something homogeneous milk chocolate milk, and some could be a heterogeneous emissions testing seattle chickpea stew, mixed with liquid and solid and more or less sausage in every spoonful. In chemistry is the same. Thus homogeneous catalysis occurs all in the same phase (typically in solution). The reactants and the catalyst are dissolved, emissions testing seattle over time, have a solution of the products and the catalyst, intact. It is a very effective catalysis, because the contact between the catalyst and chemicals is assured. Molecules in solution move freely. Presents problems, sometimes, when removing the catalyst for reuse. After mixing emissions testing seattle the chocolate milk in milk tries to separate emissions testing seattle the dust. Furthermore, heterogeneous catalysis occurs in two phases: the reagents are in solution (the stock) and the catalyst solid, is immersed in it for a while (the beans). Has a great advantage, which is widely exploited in industry: the catalyst is easily removed by simple filtration (like a sieve). But, moreover, the contact between the chemical molecules and the catalyst dissolved walk is not always straightforward. Often used to favor this contact, emissions testing seattle very solid surface. emissions testing seattle Today investigated, emissions testing seattle as I said, the two types of catalysis. In ISQCH there are also chemicals that seek to combine the advantages of each other in a mixed catalysts catalysts: emissions testing seattle solid design with attached chemical molecules.

A homogeneous catalyst is in solution with the reagents, or in the same phase as they. The catalyst is combined with one of the reactants to form an intermediate compound which reacts with the other more easily. However, the catalyst does not influence the equilibrium of the reaction, because the decomposition products in the reactants is accelerated to a similar degree. A homogeneous catalyst such as nitric oxide is used in catalyzing sulfur trioxide formation by reacting sulfur dioxide with oxygen, at the beginning and the end of the reaction the same amount of nitric oxide.
