METHOD FOR PRODUCING SACCHARIFICATION PRE-PROCESSED MATERIAL OF LIGNOCELLULOSE-BASED BIOMASS, AND SACCHARIFICATION PRE-PROCESSING DEVICE USING SAME
First Claim
1. A method for producing a saccharification pre-processed material of lignocellulose-based biomass by pre-processing lignocellulose-based biomass as a substrate prior to saccharification to yield a saccharification pre-processed material, in which lignin is dissociated from the substrate, or the substrate is swollen;
- the method comprising the steps of;
mixing the substrate with ammonia water with the concentration in a range of 20 to 30% by mass at a mass ratio of substrate;
ammonia water=1;
0.7 to 1;
1.3 to yield a substrate mixture;
heating the substrate mixture while keeping the same at a temperature in a range of 25 80 to 100°
C. for a time period in a range of 1 to 100 hours for dissociating lignin from the substrate or swelling the substrate to yield a saccharification pre-processed material containing ammonia; and
separating ammonia gas from the saccharification pre-processed material containing ammonia to yield a saccharification pre-processed material.

Abstract
A method for producing a saccharification pre-processed material capable of producing a saccharification pre-processed material, in which lignin is sufficiently dissociated, when lignocellulose-based biomass is pre-processed with ammonia water, and a pre-processing device used therefor are provided. A saccharification pre-processing device 1 comprises a processing means 2 for mixing a substrate with ammonia water with the concentration from 20 to 30% by mass at a mass ratio of substrate:ammonia water=1:0.7 to 1:1.3 to yield a substrate mixture; heating the substrate mixture while keeping the same at a temperature of 25 to 100° C. for 1 to 100 hours for dissociating lignin from the substrate or swelling the substrate to yield a saccharification pre-processed material containing ammonia; and separating ammonia from the saccharification pre-processed material containing ammonia to yield a saccharification pre-processed material; and an ammonia water supplying means 4 for supplying ammonia water to the processing means 2.
