NOVELTY - A biomass processing apparatus (A) has a pressurized hot water reaction apparatus (1), a primary catalytic reaction apparatus (2) which produces monosaccharide liquid (LL) containing xylose by hydrolyzing polysaccharide liquid (JJ) which flows out of pressurized hot water reaction apparatus using a solid acid catalyst (FF), and a secondary catalytic reaction apparatus (3) which produces monosaccharide liquid (GG) containing glucose by hydrolyzing polysaccharide liquid (DD) which flows out of pressurized hot water reaction apparatus using a solid acid catalyst.    USE - Apparatus is used for processing biomass (claimed).    ADVANTAGE - The apparatus easily and efficiently enables processing of biomass with reduced number of pipelines. The generation of substance which inhibits ethanol fermentation is suppressed.    DETAILED DESCRIPTION - A biomass processing apparatus has a pressurized hot water reaction apparatus, a primary catalytic reaction apparatus which produces monosaccharide liquid (LL) containing xylose by hydrolyzing polysaccharide liquid (JJ) which flows out of pressurized hot water reaction apparatus using a solid acid catalyst, and a secondary catalytic reaction apparatus which produces monosaccharide liquid (GG) containing glucose by hydrolyzing polysaccharide liquid (DD) which flows out of pressurized hot water reaction apparatus using a solid acid catalyst. The apparatus produces polysaccharide liquid containing xylo oligosaccharide by hydrolyzing biomass (AA) on primary reaction conditions for decomposition of hemicellulose using pressurized hot water, and produces polysaccharide liquid containing cellooligosaccharide by hydrolyzing biomass on secondary reaction conditions for decomposition of cellulose. An INDEPENDENT CLAIM is included for biomass processing method.    DESCRIPTION OF DRAWING(S) - The drawing shows the block diagram of biomass processing apparatus.
