A MULTISTEP METHOD OF PRODUCING FUELS, FUEL PRECURSORS AND CHEMICALS FROM MICROALGAE OR LIPID CONTAINING BIOMASS AND METAL BASES

摘要

Methods for producing a fuel or fuel precursor and other products from lipid-containing biomass comprising heating an aqueous slurry comprising lipids containing biomass and water in a pressure vessel in the presence of a metal base to produce a solid phase comprising one or more precipitated metal soaps and an aqueous phase, seperating the solid phase from the aqueous phase, and heating the solid phase to the decomposition temperature of the one or more metal soaps.
