摘　　要：固定床渣油加氢-催化裂化(催化裂解)组合技术是炼油厂低成本实现化工转型的重要技术。提升渣油加氢脱硫催化剂的活性和稳定性,不仅可以有效提高下游催化裂解装置的化工产品收率,而且有利于延长渣油加氢装置运转周期,进而使二者运行和检修周期更为匹配。设计活性和稳定性兼具的活性相结构,一直是重油加氢脱硫催化剂设计中的难题。从催化剂制备流程入手,系统介绍了制备过程中重要环节对活性相结构的影响规律,总结了活性相结构的调控机理,指出了从原子层面精准设计催化剂活性相结构的方法。The combination technology of fixed-bed residue hydrogenation-catalytic cracking(deep catalytic craking)is an important technology for refineries to realize low-cost chemical transformation.Improving the activity and stability of residue hydrodesulfurization catalyst can not only effectively improve the chemicals yield of the downstream catalytic cracking unit,but also help to prolong the operation cycle of the residue hydrodesulfurization unit,and then make the operation and maintenance cycle more matching for the two sets of units.It is always a difficult problem to design the active phase structure with both activity and stability of residue hydrodesulfurization catalysts.Starting with the catalyst preparation process,the effect of the important steps in the preparation process on the structure of active phase was systematically introduced,the regulation mechanism of the active phase structure was summarized,and the method of accurate design of active phase structure of the catalyst with both active and stability from atomic level was pointed out.
