IMPROVED PROCESS FOR CONVERTING BIOMASS ALGALE TO A GAS OR BIO-CRUDE RESPECTIVELY BY GASIFICATION OR HYDROTHERMAL LIQUEFACTION

摘要

The invention relates to a process for converting algal biomass into a gas or a bio-crude for the production of a fuel or a fuel, in particular a liquid fuel, or other synthetic product, comprising the following steps: hydrothermal gasification or hydrothermal liquefaction of an algal biomass in at least a first reactor, b / separation between respectively the gas or the biocrude product, and the aqueous effluents and the CO2 produced at the outlet of the first reactor, c / recovery of aqueous effluents, d / oxidation of aqueous effluents in at least a second reactor.
