Title:
METHOD FOR PRODUCING SUGAR FROM CELLULOSE AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/216288
Kind Code:
A1
Abstract:
The present invention pertains to a method that is for producing a sugar from a cellulose raw material, the method including subjecting the cellulose raw material to electrolysis in the cathode tank to obtain the sugar by using a two-chamber electrolysis tank in which a cathode chamber and an anode chamber are separated from each other by a diaphragm. The diaphragm is a proton conductive membrane. The cathode in the cathode chamber contains a graphite structure. At least a portion of the surface of the cathode has a graphene structure, and the cathode contains a carbon material having an oxygen-containing functional group. The present invention provides a cellulose saccharification production method which can be used for various and dispersed biomass raw materials, does not require expensive high-pressure equipment, and can be performed at room temperature and under atmospheric pressure.
