Abstract

Disclosed is a solid-acid-catalyzed saccharification device (A) provided with: a catalysis vessel (3), containing a polysaccharide feedstock in a mixture (X3) with water and a solid acid catalyst (X2), which uses the solid acid catalyst (X2) to convert the polysaccharide into a monosaccharide; an agitation device (4) which agitates the liquid mixture (X3) in the catalysis vessel (3); an oxidation-reduction potentiometer (5) which measures the redox potential of the liquid mixture (X3) in the catalysis vessel (3); and a pH meter (6) which measures the pH of the liquid mixture (X3) in the catalysis vessel (3). This solid-acid-catalyzed saccharification device (A) makes it possible to accurately follow the reaction state of a feedstock saccharification process that uses a solid acid catalyst.

Description

technical field [0001] The invention relates to a solid acid catalyst saccharification device and method. [0002] This application claims priority based on Japanese Patent Application No. 2010-8552 for which it applied to Japan on January 18, 2010, and uses the content here. Background technique [0003] As is well known, in recent years, attention has been paid to techniques for producing ethanol (bio-ethanol) using biomass (biologically-derived organic resources other than fossil resources) as an alternative fuel for fossil fuels such as petroleum. The following Non-Patent Document 1 discloses a technology of saccharification of biomass using a solid acid catalyst as a key technology in the production process of such bioethanol. [0004] In this biomass saccharification technology, for example, cellulosic biomass is decomposed and saccharified by combining a catalyst (solid acid catalyst) carrying a sulfo group on a carrier such as carbon or zeolite and a hydrothermal re...
