阐述了催化剂中活性金属和助剂的种类及含量对催化剂性能的影响;总结了活性金属和助剂对金属-载体相互作用、催化剂酸分布以及催化剂表面性质的影响机制。指出制备一个性能优良的催化剂应从两方面入手,首先是制备一个性能优良的载体,要求它具有合适的孔分布和酸分布,负载的金属应具有较高的分散度和还原性能。探讨了适于煤焦油的加氢处理催化剂,主要是防止催化剂的中毒、积炭、失活,并且协调各种催化剂同步失活,以利于整个装置运行周期的延长。旨在为煤焦油加氢精制和加氢裂化催化剂研究（设计）提供一定的理论指导,避免焦油加氢精制和加氢裂化催化剂研究和开发的盲目性。

This paper described the influences of the type and content of active metal and promoter in catalytic performances,and summarized the regulating mechanisms of active metal and promoter on the catalyst’s metal-carrier interaction,acids distribution and surface properties.To prepare a catalyst with good performance,two aspects should be considered,i.e.an excellent carrier with proper pores distribution and acids distribution,and a loaded active metal with high dispersion degree and outstanding reduction performance.We discussed the suitable hydrotreating catalyst for coal tar,mainly focusing on preventing catalyst poisoning,carbon deposit,and deactivation,as well as inactivating the hydrotreating catalysts synchronously in order to prolong the operation cycle of entire unit.The paper aims at providing some theoretical guidance for the research(design) of coal tar hydro-refining and hydrocracking catalysts so as to avoid the research and development blindness.
