SACARIDE SOLUTION PRODUCTION SYSTEM USING A BIOMASS RAW MATERIAL AND METHOD TO PRODUCE A SACARIDE SOLUTION USING A BIOMASS RAW MATERIAL

摘要

Summary “Biomass hydrothermal decomposition system, method of producing saccharide solution using biomass feedstock, and alcohol production method using biomass feedstock” provided is a hydrothermal biomass decomposition system that includes: one unit biomass supply 12 providing a biomass feedstock 11 containing cellulose, hemicelluloses and lignin at a pressure ranging from normal pressure to an added pressure; hydrothermally decompose biomass feedstock 11 using pressurized hot water (hereinafter also referred to as "hot water") 15; a hydrothermal decomposition unit 17 that dissolves lignin components and hemicellulose components in pressurized hot water 15; a biomass solid fraction discharge unit 18 that discharges a biomass solid fraction 20 from hydrothermal decomposition unit 17; an enzymatic liquefaction tank 21 which is in connection with the biomass solid fraction discharge unit 18, and into which the discharged solid biomass fraction 20 is introduced, and an enzyme 30 is supplied to the biomass solid fraction 20 to liquefy the solid biomass fraction 20; and a discharge unit 23 which discharges the solid fraction of liquefied biomass 24 at a pressure ranging from a pressure added to normal pressure.
