Saccharide solution production system, saccharide solution production method using biomass raw material, and alcohol production method using biomass raw material

摘要

Provided is a biomass hydrothermal decomposition system which includes: a biomass supply unit that supplies a biomass raw material; hydrothermally decomposing the biomass raw material using pressurized hot water; a hydrothermal decomposition unit that dissolves lignin components and hemicellulose components in the pressurized hot water; a biomass solid fraction discharge unit that discharges a biomass solid fraction from the hydrothermal decomposition unit; an enzymatic liquefaction tank that is in connection with the biomass solid fraction discharge unit, and in which the discharged biomass solid fraction is introduced, and an enzyme is supplied to the biomass solid fraction to liquefy the biomass solid fraction; and a discharge unit that discharges the liquefied biomass solid fraction.
