A hydrothermal decomposition apparatusas a biomass processing apparatus that decomposes a biomass materialinto cellulose, hemicellulose, and lignin under a high temperature and high pressure condition to remove a lignin component and a hemicellulose component, a biomass solid discharging unitthat discharges a biomass solid (a hot-water insoluble component)processed in the hydrothermal decomposition apparatus, and a slurrying vesselcommunicating with the biomass solid discharging unit, into which wateris injected and the discharged biomass solidis added to make it slurried are provided to an apparatus body, which is a processing vessel having a gas-liquid interface

Biomass processing system and saccharide-solution production method using biomass material

A saccharide-solution production method using a biomass material, including feeding a biomass material containing cellulose, hemicellulose, and lignin under a normal pressure to put it under an increased pressure; hydrothermally decomposing the biomass material using pressurized hot water by a hydrothermal decomposition unit; and dissolving a lignin component and a hemicellulose component in the pressurized hot water; thereafter, adding a biomass solid discharged from the hydrothermal decomposition unit to a slurrying vessel containing water injected therein and communicating with the hydrothermal decomposition unit so as to obtain a slurried biomass solid; then, removing water from the slurried biomass solid; and thereafter, performing enzymatic saccharification of the water-removed biomass solid to produce a saccharide solution.

Biomass hydrothermal decomposition system and saccharide-solution production method using biomass material

A biomass hydrothermal decomposition system includes a hydrothermal decomposition unitthat transports the fed biomass material from a lower side to an upper side in an apparatus bodyby screw means, feeds pressurized hot waterfrom an upper side different from a feed position of the biomass materialinto the apparatus body, which is pressurized hot water to be discharged, so as to separate a lignin component and a hemicellulose component from the biomass material; a biomass solid discharging unitthat discharges a biomass solidfrom the upper side of the apparatus body; and a slurrying vesselcommunicating with the biomass solid discharging unit, into which wateris injected and the discharged biomass solidis added to obtain a slurried biomass solid are provided.

A biomass processing system includes: a hydrolysis processing unit that decomposes, under a high-temperature/high-pressure condition, biomass feedstock in a processing tank having a gas-liquid interface, and removes a lignin component and a hemicellulose component; a biomass solid content discharge unit that discharges a biomass solid contentwhich is a hot water insoluble element; a slurrying vessel that subjects the discharged biomass solid content to slurrying; and a hot water discharge liquid introducing line Lthat introduces, into the slurrying vessel, a hot water discharge liquidincluding a biomass hot-water soluble element.
