Biomass treatment system, saccharide solution producing process using biomass as raw material, and organic raw material producing process

摘要

This biomass treatment system includes: a hydrothermal decomposition section (17) for decomposing the cellulose, hemicellulose and lignin contained in a biomass (11) as a raw material under high-temperature and high-pressure conditions in a main section (13), namely a tank having a gas-liquid interface (13a), and thus removing a lignin component and a hemicellulose component from the biomass (11); a discharge section (18) for discharging a biomass solid component (20) (a component insoluble in hot-water) obtained by the decomposition; a slurrying tank (21) which is connected to the discharge section (18) and in which the discharged biomass solid component (20) is slurried in water (19) fed thereinto to form a biomass solid component slurry (24); and a solid-liquid separation apparatus (30) including both a settling tank (31) which is provided on a discharge line (L
