TREATMENT PROCESS AND INSTALLATIONnOF LIGNOCELLULOSIC BIOMASS AND USE OF THE PROCESS OR INSTALLATION. THEnThe present invention relates to a biomass treatment processnlignocellulosic material comprising, successively, b) a step ofnpre-treatment of the biomass previously placed in acidic conditions or innneutral pH in a pre-treatment reactor (3), to produce bagassenacidic (MA) or neutral pre-treated, alternating with b') a step ofnpre-treatment of the biomass previously placed in acidic conditions,nneutral or basic, with eventual introduction sufficient in the reactor ofnpre-treatment (3) of a basic aqueous solution (EB), to produce anbasic pre-treated bagasse (MB), then c) a hydrolysis stepnenzyme in a hydrolysis reactor (16) of a mixture of bagassenacidic (MA) or neutral pre-treated from step b) with bagassenbasic pre-treated (MB) from step b'). |
