摘　　要：纤维素直接催化转化制乙二醇是一条极具吸引力的生物质转化途径,有助于减轻化石能源资源的消耗。综述了从该反应途径的发现到获得高效、高稳定性催化剂的快速发展过程。基于对钨基催化剂的大量研究结果,本文讨论了反应机制,明确了反应路径、催化剂状态、钨物种及加氢催化活性中心各自在串联反应中的作用。围绕该反应过程的工业化应用需要,讨论了有关原生木质纤维素生物质催化转化以及高效反应过程的发展策略。在此基础上,将纤维素催化转化制乙二醇过程与生物质发酵制丙酮-丁醇-乙醇的生物炼制路线进行整合,构建出一个理想的反应过程潜在应用范例。最后,对纤维素催化转化制乙二醇反应过程进行了总结和前景展望.The one-pot catalytic conversion of cellulose to ethylene glycol （CEG） is a highly attractive way for biomass utilization to lessen the consumption of fossil energy resources. In this paper, we reviewed the disclosure of the CEG process and the rapid progress in the development of highly efficient and robust catalysts for it. Based on our study of tungstenic catalysts, we discuss the reaction mecha-nism, in which the reaction routes, catalyst states, and catalytic roles of the tungsten species and hydrogenation sites in the cascade reactions are understood clearly. With future applications in mind, the conversion of raw cellulosic biomass and the strategy to develop an efficient CEG process for commercialization are discussed, and a model where the CEG process is incorporated into a bio-refinery process of acetone-n-butanol-ethanol （ABE） production is presented.
