重点阐述了加氢催化剂的活性组分与载体对多环芳烃催化加氢性能的影响，同时综述了选择性催化加氢反应机理，研究发现，多环芳烃催化加氢受到活性组分的分散性和颗粒大小、载体酸性和孔道分布的影响，最后指出了加氢催化剂开发应关注的内容。

The effects of the active components and carrier of hydrogenation catalysts on the catalytic performance of the catalysts in hydrogenation of polycyclic aromatic hydrocarbons (PAHs) are expounded,and reaction mechanism are discussed.It is found that the performance of catalysts can be impacted by the distribution and particle size of active components,and the acid and structure of carrier.Some suggestions for the development of catalyst for selective hydrogenation of PAHs are given.
