摘　　要：重整催化剂活性要求其酸性功能和金属功能稳定,而在连续再生过程中,烧焦会导致催化剂Pt金属聚集、氯含量降低,氧氯化区有效操作是恢复催化剂活性的关键因素之一。文章介绍了四川石化2041kg·h^(-1)催化剂连续再生装置氧氯化区运行遇到的问题和处理方法,供需要提高氧氯化效果的装置参考。The activity of reforming catalyst requires its acid and metal function to be stable.In the process of cyclemax catalyst regeneration,the coking will lead to the agglomeration of Pt metals and the reduction of chlorine content.Effective chlorination zone operation is one of the key factors to recover catalyst activity.This article will show the problems encountered in the operation of thechlorination zone in the 2041kg·h^(-1) cyclemax catalyst regeneration unitin Petrochina Sichuan Petrochemical Co.,Ltd.,and pertinentsolutions.This couldprovide somesuggetstions for those unitswho need to improve its chlorination effect.
