Patent ID: 10450698

Abstract:
The method for producing a cellulose-containing solid material of the invention includes treating a botanical biomass in a mixed solvent of water and at least one alcohol selected from aliphatic alcohols having 4 to 8 carbon atoms, under condition A (the concentration of the raw material to be charged into the mixed solvent is 1% by mass or more and 50% by mass or less), condition B (the reaction temperature is 100° C. or higher and 350° C. or lower), and condition C (the reaction time is 0.1 hours or more and 10 hours or less), followed by solid-liquid separation after the treatment to give a cellulose-containing solid material. Accordingly, there are provided a method for producing a cellulose-containing solid material excellent in saccharification performance and a method for producing glucose from the cellulose-containing solid material.
