预处理在纤维素的衍生物反应和功能化过程中起着非常重要的作用,是利用纤维素生产燃料乙醇的关键步骤。纤维素预处理技术的改进对提高纤维素的水解率,降低燃料乙醇的生产成本有着重要意义。综述了超临界水法和离子液体法预处理纤维素技术的国内外研究进展,并对纤维素预处理技术的发展前景进行了展望。
Pretreatment plays a very important role in the reaction and functionalization of cellulose derivatives and is a key step in the production of fuel ethanol from cellulose. The improvement of cellulose pretreatment technology is of great significance to improve the hydrolysis rate of cellulose and reduce the production cost of fuel ethanol. The progress of the research on cellulose technology pretreatment by supercritical water and ionic liquid is reviewed. The development prospect of cellulose pretreatment technology is also forecasted.
