Key words: biodiesel, bioethanol, supercritical media
Economical and technical aspects of liquid motor fuel production from renewable raw materials and its prospects for such technologies in Russia and worldwide are reviewed. The data on economical efficiency of bioethanol and biodiesel production in supercritical (SC) media are analyzed. Trans-esterification of vegetable and seed oils using SC methanol (ethanol) is compared with "conventional" catalytic process, and possible ways of cutting the production costs and rising the profitability of the process in SC media are discussed.
