Abstract

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.

Abstract

A method for producing an algal biomass that readily separable from water, and preferably sterile, the method comprising heating an aqueous slurry of algae comprising a mixture of an algal biomass, optionally together with a suitable separation agent, and water in a pressure vessel at a temperature of about 140°C to about 300°C and a pressure sufficient to maintain the liquid phase. The method produces an algal biomass that is more readily separable from water and an aqueous phase containing organic chemicals.
