摘要
由于纤维素是世界上最丰富的生物质能源资源,纤维素的资源化利用是当前国内外的研究重点。迄今为止,利用酶、稀酸及超临界水对纤维素进行催化降解已有大量的研究,但是这些方法都存在明显的缺点,例如产物和催化剂分离困难、酸的强腐蚀性、废液处理难以及反应条件苛刻等。为了克服以上缺点,开发新的催化体系对纤维素进行高效降解和转化成为了当前国内外的研究热点。综述了近年来国内外纤维素催化转化双功能催化体系的研究进展。
Cellulose is the most abundant source of biomass in the world, so resource utilization of cellulose has become a hot topic. Thus far, a great deal of effort has been put into the degradation of cellulose with enzymes, dilute acids, and supercritical water, but these processes have significant shortcomings such as difficult separation of products and catalysts, corrosion hazard, and severe controls of waste fluids and reaction conditions. Therefore, in order to achieve efficient cellulose degradation by overcoming above-mentioned disadvantages, developing a new catalytic system has become more popular. The bifunctional catalytic conversion of cellulose is summarized at home and abroad.
