摘　　要：乙酸甲酯加氢制乙醇是合成气间接制乙醇工艺中的重要一步,其关键在于催化剂的开发,工业上主要应用铜基催化剂。铜基催化剂的催化性能与其微观结构密切相关,调变催化剂结构可以有效调控其催化性能。综述了乙酸甲酯加氢制乙醇铜基催化剂的研究进展,归纳总结了引入助剂、载体调变、制备方法优化和特殊结构设计等结构调变策略对催化剂性能的调控作用。在此基础上,对低温、低氢酯比(物质的量之比)条件下高效稳定的乙酸甲酯加氢制乙醇铜基催化剂的开发进行了展望。Methyl acetate hydrogenation to ethanol is an important step in the indirect synthesis route of ethanol from syngas.Catalyst development is the key and Cu-based catalysts are mainly used in industry.The catalytic performances of Cu-based catalysts are closely related to their microstructure.The structure modulation of catalysts can effectively adjust their catalytic performances.The research progress of Cu-based catalysts in methyl acetate hydrogenation to ethanol was reviewed,and the effects of modulation strategies on the catalytic performance were summarized,including introducing additives,modifying carriers,optimizing preparation methods and designing special structures.On this basis,developing efficient and stable Cu-based catalysts for methyl acetate hydrogenation to ethanol at low temperature and low hydrogen/ester mole ratio was prospected.
