两种新型C8芳烃异构化催化剂的工业应用

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。

INDUSTRIAL APPLICATION OF TWO NOVEL C8 AROMATICS ISOMERIZATION CATALYSTS

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.
