摘要
纤维素是一种地球上含量最丰富的可再生资源,经预处理、水解、发酵后可生产燃料乙醇。因此,纤维素水解制备糖是纤维素转化工程中关键步骤,而水解技术主要包括酸水解和酶水解两大类。对这两大类水解工艺的优缺点进行了分析和比较,指出了废弃纤维素类生物质水解的研究方向。
Cellulose is a rich renewable biomass on the earth. After pretreatment, hydrolysis and fermentation, it could be used for fuel-ethanol production. Accordingly, the key to the conversion of celluloses to bioethanol was the preparation of fermentable sugar effectively by the hydrolysis of cellulose.The main hydrolysis techniques included acid hydrolysis and enzymatic hydrolysis. In this paper, the advantages and the disadvantages of the two hydrolysis techniques were analyzed and compared. Besides, the research direction of the hydrolysis of waste cellulose biomass was put forward.
