摘要: 阐述了两种转化型C8芳烃异构化催化剂RIC-200和OPARIS PLUS(IFP技术)的工业应用对比。RIC-200是中国石化石油化工科学研究院开发的新型催化剂,OPARIS PLUS为ZEOLYST公司的新一代催化剂。通过催化剂的开工、工业标定和长周期性能等对比分析,结果表明:两种催化剂在异构化活性相当的情况下,新型RIC-200催化剂的乙苯转化率和C8烃收率优于国外剂,具有裂解少、选择性高、乙苯转化率高的特点;此外,RIC-200催化剂具有采用还原态、开工过程不需要注硫钝化、开工时间短、操作风险低、正常运转中不需要注水来调节催化剂活性的优点。

Abstract: The industrial application of two C8 aromatics isomerization catalysts, RIC-200 developed by Research Institute of Petroleum Processing and an imported catalyst represented the advanced world level, was introduced. The start-up, performance test and long-term operation of these two catalysts were compared. Industrial application results show that these two catalysts all exhibit good isomerization activity and stability; the conversion of ethylbenzene, C8 hydrocarbons yield and selectivity of RIC-200 are slightly better than those of the imported catalyst. Besides, RIC-200 catalyst is in reduced state, thus its start-up procedure is simple and the start-up period is shorten; its operation risk is low and more stable due to without water injection to adjust catalyst activity during operation.
