Preparation and saccharification pretreatment apparatus used therefor saccharification pre-treatment of lignocellulosic biomass

摘要

When it is pretreated with ammonia water lignocellulosic biomass, to provide a pretreatment apparatus used therefor, and method of manufacturing the saccharification pretreatment products obtained glycation pretreatment product lignin is sufficiently dissociated. Saccharification pretreatment device 1, a substrate, a substrate, and aqueous ammonia of 20 to 30% by mass to obtain the substrate mixture is mixed at a mass ratio of 1.3: aqueous ammonia = 1: 0.7 to 1 and heating the substrate resulting mixture at a temperature of 25~100 ℃, and held 1 to 100 hours, to dissociate lignin from the substrate, or swell the substrate, with the ammonia-containing saccharification pre-treated product obtained and processing means 2 to obtain a pre-saccharification treated product was separated ammonia from ammonia-containing saccharification pre-treatment product was, I and supplying ammonia water supply means 4 ammonia water to the processing means 2.
