Title:
METHOD FOR PRODUCING SACCHARIFICATION PRE-PROCESSED MATERIAL OF LIGNOCELLULOSE-BASED BIOMASS, AND SACCARIFICATION PRE-PROCESSING DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/142426
Kind Code:
A1
Abstract:
Disclosed is a method that is for producing a saccharification pre-processed material and that obtains a saccharification pre-processed material from which lignin has been sufficiently dissociated when preprocessing lignocellulose-based biomass by means of aqueous ammonia. Further disclosed is a pre-processing device using same. The saccharification pre-processing device (1) is provided with: a processing means (2) that mixes a substrate and 20-30 mass% aqueous ammonia at a mass ratio substrate:aqueous ammonia of 1:0.7-1:1.3, obtaining a substrate mixture, heats the obtained substrate mixture, holding at a temperature of 25-100°C for 1-100 hours, dissociates lignin from the substrate or causes the swelling of the substrate, obtaining an ammonia-containing saccharification pre-processed material, and dissociates ammonia from the obtained ammonia-containing saccharification pre-processed material, obtaining a saccharification pre-processed material; and an aqueous ammonia supply means (4) that supplies aqueous ammonia to the processing means (2).
