使用 HPLC、CPC 和 IR 分析了在近临界水中进行的纤维素分解过程中获得的产物的性质。产物的性质随着反应的进行而变化，并提出了由水溶性物质（WS）的形成过程和随后的第二次分解过程组成的反应模型。 WS形成过程是糖化过程，其中水解优先进行。第二个分解过程是WS的碳化过程，其中官能团的消除导致气态产物的形成和WS的不溶化。糖化过程中得到的水解液可以作为乙醇发酵的原料，通过活性炭处理去除糠醛，提高了该溶液的发酵率。版权所有 (C) 1997 爱思唯尔科学有限公司
The properties of the products obtained in the cellulose decomposition process conducted in near-critical water were analyzed using HPLC, CPC and IR. The properties of the products changed with the progress of the reaction and a reaction model consisting of the formation process of water solubles (WS) and the subsequent second decomposition process was proposed. The WS formation process is a saccharification process where hydrolysis preferentially progresses. The second decomposition process is a carbonization process of WS, where the elimination of functional groups leads to the formation of gaseous products and insolubilization of WS. The hydrolyzate solution obtained in the saccharification process could be used as a feedstock of ethanol fermentation and the fermentation rate of the solution was improved by removing furfurals with an active carbon treatment.
