摘　　要：高端氢化石油树脂应用广泛,市场需求逐年增加,如何实现高效生产高品质氢化石油树脂是该领域研究的重点。高品质氢化石油树脂的生产主要是采用催化加氢技术,开发高效稳定的加氢催化剂是关键的技术环节。本文针对催化剂加氢效率低、树脂分子扩散与吸附困难、加氢反应条件苛刻等问题,重点综述了近年来研究者为解决上述难点在催化剂金属活性组分组成、几何与电子结构、载体形貌与孔结构设计等方面的研究成果。提出催化剂中金属活性位点的分散度、位点分布情况、价态调控及复合金属间的协同作用是调控催化剂性能的关键。同时,对目前石油树脂加氢催化剂活性位点设计、反应机理、催化剂失活再生机制等方面进行总结并展望催化剂的未来发展方向。Hydrogenated petroleum resins have wide application in high-end fields,and the demand for high-quality petroleum resins has increased year by year.Efficient production of high-quality hydrogenated petroleum resin has become the research focus in the field.High-quality petroleum resin is mainly produced by hydrogenation of raw resin materials and efficient and stable hydrogenation catalysts are the key.However,the resin hydrogenation system still suffers from problems such as poor hydrogenation performance,low diffusion of resin in catalyst pores and harsh reaction conditions.This review summaries the research progress in terms of rational design of active components,geometric and electronic structure,support morphology and pore structure.Highlighting the effect of the dispersion of metal active sites,active sites distribution,valence states engineering together with synergy between composite metal are the key factors to regulate the performance of catalyst.At the same time,the problems such as the reaction mechanism,the deactivation and regeneration mechanism of active sites and the development trend of hydrogenation catalysts in the future were summarized.
