Given the high prices of gasoline and oil, which has caused the increase in prices of many services - such as public transport, basic foods: tortilla, bread, among others - Mexicans face this situation with difficulties: poverty reaches , with increasing force, various regions of the country. To reduce this crisis, scientists from the Benemérita Universidad Autónoma de Puebla –BUAP– have developed a pilot plant that is capable of producing biodiesel from residual oil, which reduces up to almost 90 percent of its cost, and reduces the impact environmental throughout its chemical production.
For Griselda Corro Hernández, an academic at the Laboratory of Catalysis and Energy of the Institute of Sciences, an attempt was made to find a solution to the environmental problems derived from the use and production of fossil fuels worldwide. Now, "thanks to this pilot plant, unique in the world, it is possible to obtain biodiesel with only three Mexican pesos per liter, a competitive value if contrasted with the commercial price of diesel –20 pesos in the market."
It is an innovation project in an "excellent opportunity niche in the industry, as it is a technology transfer project suitable for the current situation." It was done after seven years of laboratory work, five of which were to find a catalyst that would transform cooking oil into fuel safely and economically. Once it was found, an "unprecedented process to produce biodiesel was carried out based on that finding and the incorporation of solar panel systems, as well as other innovations that resulted in a safer, cheaper and more sustainable process than any other."
The pilot plant, in which there are already in the universities of Guadalajara, Autónoma de Yucatán, Autónoma de Nuevo León and the Center for Research and Assistance in Technology and Design of the State of Jalisco, has two reactors: the first, in which the the residual oil enters, for the catalytic process - currently patented -; and the second, to clean and dry the fuel obtained from the previous reactor. And being a system of solar panels, water is heated and produces electrical energy to carry out the series of control and support mechanisms.
