摘　　要：纤维素是自然界中广泛存在的生物质资源,以纤维素为原料催化加氢制备生物基化合物是纤维素利用的重要方向。简述了纤维素的化学结构及其催化加氢反应机理;详述了纤维素的催化加氢及其所用固体金属催化剂的研究进展;纤维素催化加氢可制备C2~C6糖醇类化合物,主要采用金属催化剂,如贵金属、镍基及钨基催化剂,对比了催化剂活性组分负载于不同载体时对催化剂活性的影响;指出催化加氢将是纤维素应用研究的热点,开发高催化活性的双功能催化剂将是今后催化剂研究的重点方向。Cellulose is one of the most abundant biomass resources in nature. The catalytic hydrogenation conversion of cellu- lose into biological compound play an important role in the biomass utilization. The chemical structure of cellulose and the reaction mechanism of catalytic hydrogenation were briefly introduced. The research progress in the catalytic hydrogenation of cellu- lose and the applied solid metal catalysts was described in details. Cellulose can be produced into C2 - C6 sugar alcohol com- pounds by catalytic hydrogenation over metal catalysts, like noble metal, nickel and tungsten-based catalysts. The effects of the different carriers supporting catalyst active component on the catalyst activity were contrasted. It was pointed out that the cellulose application and catalyst research should be focused on the catalytic hydrogenation of cellulose and the high-activity bifunctional catalysts in the future.
