摘　　要：硫对重整催化剂既有坏的作用又有好的作用。硫在一定的条件下是现代双金属催化剂最持久的毒物;但是,重整开工时,对催化剂还要进行预硫化;正常生产中还保证重整进料油中含有微量硫,保持催化剂的稳定性和选择性。通过舟山石化重整装置一次硫中毒事件的发生及恢复的过程深入地分析流程重整反应的重要性及总结出相关的应对方法。Sulfur has a good effect on reforming catalyst.Sulphur is a modern bimetallic catalyst the most persistent toxic substances in certain conditions;however,the reorganization started,but also on the catalyst presulfurizing;normal production also ensure reforming feed oil containing trace sulfur,keep the catalyst stability and selectivity.Based on the analysis of the process of the occurrence and recovery of sulfur poisoning event in Zhoushan Petrochemical reforming unit,this paper analyzes the importance of the process reforming reaction and summarizes the corresponding countermeasures.
