Title:
SOLID-ACID-CATALYZED SACCHARIFICATION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2011/087131
Kind Code:
A1
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.
