BIOMASS HYDROTHERMAL DECOMPOSITION SYSTEM, SUGAR SOLUTION PRODUCTION METHOD USING BIOMASS STARTING MATERIAL, AND ALCOHOL PRODUCTION METHOD USING BIOMASS STARTING MATERIAL

WIPO Patent Application WO/2014/010048

A1

A biomass hydrothermal decomposition system comprising: a biomass supply unit (12) that supplies a biomass starting material (11) under atmospheric pressure to elevated pressure, said biomass starting material (11) containing cellulose, a hemicellulose, and lignin; a hydrothermal decomposition unit (17) that hydrothermally decomposes the biomass starting material (11) using pressurized hot water (15) (hereinafter referred to as "hot water" too) so as to dissolve the lignin component and the hemicellulose component in the pressurized hot water (15); a biomass-solid extraction unit (18) that extracts biomass solids (20) from the hydrothermal decomposition unit (17); an enzymatic liquefaction tank (21) that communicates with the biomass-solid extraction unit (18) and, when the extracted biomass solids (20) are added, supplies an enzyme (30) to the biomass solids (20) to liquefy the biomass solids (20); and a discharge unit (23) that discharges the thus liquefied biomass solids (24) under elevated pressure to atmospheric pressure.
