摘要

围绕合成气制乙醇工艺的研究现状进行了综述，介绍了直接法制备的反应机理与不同催化剂在反应中的应用，间接法中的2种不同工艺路线以及沸石催化剂在甲醇羰基化和二甲醚羰基化过程中的反应机理，并且描述了不同催化剂的开发与应用以及间接法串联床层催化的研究。

Abstract

Research status of syngas to ethanol process is reviewed.The reaction mechanism of direct preparation and the application of different catalysts in the reaction are introduced.The reaction mechanism of two different indirect process routes and zeolite catalysts in the process of methanol carbonylation and dimethyl ether carbonylation are also introduced.The development and application of different catalysts, and the study on indirect series bed catalysis are described.
