Latest Patents

Qishi Du holds a patent titled "Method for hydrolyzing cellulose into sugar to produce spherical capacitive carbon." This method focuses on the deep utilization of biomass and carbon materials. The process includes several steps: crude cellulose pretreatment, alkaline hydrolysis of cellulose, separation of cellulose from hydrolyzed sugar liquor, drying of alkali-containing hydrolyzed sugar, sintering of spherical capacitive carbon, capacitive carbon post-processing, and alkali recycling. This innovative approach utilizes biomass as a raw material, yielding high-purity cellulose and hydrolyzed sugar through deep hydrolysis. The spherical capacitive carbon is produced using hydrolyzed sugar instead of traditional sucrose and starch, ensuring that pollution and waste are minimized. Remarkably, over 80% of the alkali used in the process can be recycled.
