Title:
METHOD AND APPARATUS FOR PRODUCTION OF SACCHARIFIED SOLUTION OF CELLULOSE-TYPE BIOMASS
Document Type and Number:
WIPO Patent Application WO/2012/056872
Kind Code:
A1
Abstract:
[Problem] To provide a saccharified solution production method and a saccharified solution production apparatus, both of which can produce a saccharified solution from a cellulose-type biomass raw material by an enzymatic saccharification technique with high efficiency.
[Solution] The apparatus comprises: a first enzymatic saccharification device (21) for enzymatically saccharifying a fine powder of a cellulose-type biomass raw material (10); a first solid/liquid separation device (31) for separating into a solid material (61) which contains unsaccharified cellulose, hemicellulose, lignin and the like discharged from the first enzymatic saccharification device (21) and a liquid (63) which contains a hexose; a hot water treatment device (41) for treating the solid material (61) which has been separated by the first solid/liquid separation device (31) and contains unsaccharified cellulose, hemicellulose, lignin and the like with hot water while applying a pressure; a second solid/liquid separation device (32) for separating into a solid material (62) which contains undissolved cellulose discharged from the hot water treatment device (41) and a liquid (64) in which lignin and hemicellulose are dissolved; and a second enzymatic decomposition device (22) for enzymatically saccharifying the cellulose contained in the solid material (62) which has been separated by the second solid/liquid separation device (32) to thereby enzymatically decompose the cellulose into a saccharified solution (13) which contains the hexose.
