Abstract
The invention relates to a method for hydrolyzing the plant fiber material to produce and separate a saccharide including glucose. The method includes a hydrolysis process of hydrolyzing cellulose contained in the plant fiber material and producing glucose in a first organic solvent having a cluster acid catalyst dissolved therein.
Claims11
A method for hydrolyzing a plant fiber material to produce and separate a saccharide including glucose, comprising:
- a hydrolysis process of hydrolyzing cellulose contained in the plant fiber material and producing glucose in an organic solvent in which a cluster acid catalyst is dissolved, and
- a saccharide separation process of separating a reaction mixture after the hydrolysis process into a liquid fraction including the cluster acid catalyst and the organic solvent and a solid fraction including the saccharide,
- wherein the organic solvent is an alcohol having 6 to 10 carbon atoms, and is a high-boiling polar organic solvent that has a boiling point higher than a reaction temperature in the hydrolysis process and hardly dissolves the saccharide.
