Title:
LIGNOCELLULOSIC BIOMASS SACCHARIFICATION PRE-TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/070817
Kind Code:
A1
Abstract:
Provided is a lignocellulosic biomass saccharification pre-treatment device that can easily recover and re-use aqueous ammonia that is used for pre-treatment when saccharifying lignocellulosic biomass. The lignocellulosic biomass saccharification pre-treatment device is provided with a mixing means (2) that mixes the lignocellulosic biomass and ammonia, a heating means (3) that heats the biomass-ammonia mixture, a separating means (4) that separates ammonia gas from the biomass-ammonia mixture and obtains a biomass-water mixture, and a transport means (6) that transports the biomass-water mixture to a post-process (5). The device is provided with an aqueous ammonia-supplying means (8) that supplies aqueous ammonia to the mixing means (2), an ammonia recovery means (20) that recovers the ammonia gas as aqueous ammonia, a heat of solution recovery means (24) that recovers the heat of solution generated when the ammonia gas is dissolved in water, and a heat pump means (30) that uses at least said heat of solution as a heat source and generates heat that is supplied to the heating means (3).
