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
