Abstract:
A highly efficient reactor with a stirring device was specially designed with the intent of performing the hydrolysis of pure crystalline cellulose using a carbon-based solid acid catalyst. This catalyst comprised an amorphous carbon-based material bearing -SO3H, -COOH and -OH groups. The stirring apparatus had seven blades coated with polytetrafluoroethylene and arranged axially at regular intervals with a 60° offset. This design proved highly effective, providing double the glucose yield compared with conventional stirring systems. The basic properties of this novel reactor were investigated and analyzed and are discussed herein.
摘要:
为了使用碳基固体酸催化剂进行纯结晶纤维素的水解,特别设计了具有搅拌装置的高效反应器。该催化剂包含带有SO3H的无定形碳基材料,-COOH和-OH基团。该搅拌装置具有七个涂覆有聚四氟乙烯的叶片,并且以60°偏移的规则间隔轴向布置。这个设计被证明是非常有效的,提供两倍的葡萄糖产量相比,传统的搅拌系统。本文对这种新型反应器的基本性能进行了研究和分析,并进行了讨论。
