摘　　要：催化加氢反应是合成高附加值精细化学品的重要方法之一。加氢反应催化剂多以金属负载型催化剂为主,常用的载体主要为金属或非金属氧化物。然而受传统金属负载和掺杂方式的限制,金属负载型催化剂中活性金属的落位和粒径分布一直缺乏有效的调控手段,极大限制了该类催化剂的应用。分子筛因其独特的孔道结构、适宜的酸性、可控的孔径和表面性质常被作为载体用于催化加氢反应。在这类反应中,分子筛既可以作为载体负载活性金属,也可以作为酸性催化剂适度参与反应,表现出优异的催化加氢活性和反应稳定性。详细总结了近年来以分子筛为载体的双功能催化剂在催化加氢反应中的最新研究进展,并重点介绍了分子筛的孔道结构调控、活性金属负载方式以及加氢反应类型变化对加氢反应的影响。Catalytic hydrogenation reaction has become one of the important methods to synthesize high value-added fine chemicals.The hydrogenation reaction is mainly based on metal-supported catalysts,and the commonly used carriers are dominated by metal or non-metal oxides.However,due to the limitations of traditional metal loading and doping methods,there is a lack of effective means to control the site and particle size of active metals in metal-supported catalysts,which greatly limits the application of such catalysts.Molecular sieves are often used as carriers for catalytic hydrogenation because of their unique pore structure,suitable acidity,controllable pore size and surface properties.In the hydrogenation reaction,molecular sieve not only can be a carrier to load active metals but also sometimes can moderately take part in the reaction as an acidic catalyst.These catalysts exhibit excellent catalytic hydrogenation activity and reaction stability.The paper detailedly summarizes the latest research progress in the catalytic hydrogenation of bi-functional catalysts supported by molecular sieves,and mainly introduces the influence of pore structure regulation of molecular sieves,active metal loading method and hydrogenation reaction type on hydrogenation reaction.
