PROCESS FOR THE PREPARATION OF BIOFUEL BYDECARBOXYLATION OF NATURAL CARBOXYLIC ACIDSRomanova Anastasiya, Shvets Valeriy, Suchkov Yury, Korneev IgorD.I. Mendeleev University of Chemical Technology of Russia, Mosсow,Miusskaya sq., 9, liceistka2003@mail.ruPP-49The world’s fossil fuel resources – including crude oil, natural gas and coal – arehuge, however they will be exhausted sooner or later. There is already fossil fueldeficit leading to a rise of motor fuel prices. As a result use of renewable energysources expands steadily. Thus, the most significance acquires a biofuel producedfrom vegetable oils, animal fats, or its derivatives, particularly, fatty acids.In literature there are a lot of works devoted to the process of producing thebiofuel engine (biodiesel, ethanol, methanol etc.) In the current report we presentresults of investigation of process for production of biofuel by decarboxylation of fattyacids, which in perspective should be a key stage in obtaining hydrocarbonscontaining 15-21 carbon atoms. This type of fuel can be termed as biofuel IIgeneration.The influence of reaction conditions (such as temperature, pressure, catalyst typeand feed rate of stock) on conversion and selectivity of process decarboxylation offatty acids was investigated and optimal ranges of these parameters weredetermined.As a catalyst the series of compounds from a number of industrial catalysts ofhydrorefining, individual and supported zeolites and many others, were tested. It wasfound that the most efficient catalysts are γ-alumina and supported zeolites, whichcan be recycled.139
