Abstract

The invention relates to: a pre-treatment method for plant biomass hydrolysis reaction raw materials characterized in comprising a process for mixing a solid catalyst and solid substrate beforehand and grinding same simultaneously (grinding process); a plant biomass hydrolysis reaction raw material pre-treated by said pre-treatment method; and a plant biomass saccharification method comprising a process for hydrolyzing said hydrolysis reaction raw material. The invention provides an efficient and practical pre-treatment method for plant biomass hydrolysis reaction raw materials that can improve the saccharification yield and saccharide concentration of plant biomass hydrolysis reactions, a plant biomass hydrolysis reaction raw material obtained therefrom, and a plant biomass saccharification method.

Claims (9)

1. A pre-treatment method for a plant biomass hydrolysis reaction raw material, comprising pulverization step that comprises simultaneously mixing and pulverizing a solid catalyst and a solid substrate,

in which the solid catalyst is a carbon material which is alkali-activated carbon, steam-activated carbon, or mesoporous carbon and

in which a median diameter of a mixture of the solid catalyst and the solid substrate as the reaction raw material after the pulverization step is 1 to 30 micrometer.

2. The pre-treatment method for a plant biomass hydrolysis reaction raw material according to claim 1 , in which the solid substrate is a polysaccharide derived from a plant biomass.

3. The pre-treatment method for a plant biomass hydrolysis reaction raw material according to claim 1 , in which the pulverization step is carried out using a tumbling ball mill, a vibrating ball mill, a mixing mill, or a planetary ball mill.

4. The pre-treatment method for a plant biomass hydrolysis reaction raw material according to claim 1 , in which a mass ratio between the solid catalyst and the solid substrate is 1:100 to 10:1.

5. The pre-treatment method for a plant biomass hydrolysis reaction raw material according to claim 4 , in which a mass ratio between the solid catalyst and the solid substrate is 1:10 to 1:1.

6. A plant biomass hydrolysis reaction raw material, which is treated by the pre-treatment method according to claim 1 .

7. A saccharification method for a plant biomass, comprising the step of hydrolyzing the hydrolysis reaction raw material according to claim 6 .
