IMPROVED METHOD FOR CONVERTING ALGAL BIOMASS INTO A GAS OR INTO BIOCRUDE BY HYDROTHERMAL GASIFICATION AND HYDROTHERMAL LIQUEFACTION, RESPECTIVELY

摘要

The invention relates to a method for converting algal biomass into a gas or into biocrude in order to produce a combustible material or a fuel, especially a liquid fuel, or another synthesis product, said method comprising the following steps: a) hydrothermal gasification or hydrothermal liquefaction of an algal biomass in at least one first reactor, b) separation of the gas or biocrude produced thereby from the aqueous effluents and the CO2 produced, at the outlet of the first reactor, c) recovery of the aqueous effluents, and d) oxidation of the aqueous effluents in at least one second reactor.
