摘要： A method for hydrolyzing cellulose into sugar to produce spherical capacitive carbon for the deep utilization of biomass and carbon materials. The present disclosure includes the following steps of: (1) crude cellulose pretreatment; (2) alkaline hydrolysis of cellulose; (3) separation of the cellulose from a hydrolyzed sugar liquor; (4) drying of an alkali-containing hydrolyzed sugar; (5) sintering of spherical capacitive carbon; (6) capacitive carbon post-processing; and (7) alkali recycling. In the method, biomass is used as a raw material, high-purity cellulose and hydrolyzed sugar are obtained through deep hydrolysis, the spherical capacitive carbon is sintered with the hydrolyzed sugar instead of sucrose and starch, and alkali is recycled. Pollution and waste are not generated, and more than 80% of the alkali can be recycled.
