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. L'invention concerne des procédés permettant de produire un combustible ou un précurseur de combustible et d'autres produits à partir d'une biomasse contenant des lipides, lequel procédé consiste à chauffer une boue aqueuse comprenant une biomasse contenant des lipides et de d'eau dans un récipient sous pression en présence d'une base métallique afin de produire une phase solide comprenant un ou plusieurs savons métalliques précipités et une phase aqueuse, à séparer la phase solide de la phase aqueuse, puis à chauffer la phase solide à une température de décomposition d'un ou de plusieurs savons métalliques.
