低铂脱乙基型C8芳烃异构化催化剂的工业应用

介绍了中国石化石油化工科学研究院开发的降低贵金属Pt负载量的SKI-110乙苯（EB）脱乙基型C8芳烃异构化催化剂的工业应用情况。结果表明，降低Pt含量后，SKI-110催化剂的对二甲苯（PX）异构化率达到23.04%，单程乙苯转化率达到70.40%，单程二甲苯收率大于98%。该催化剂满足工业装置产品需求、有效地降低了PX生产成本,实现了联合装置操作中降低能耗的目标。

COMMERCIAL APPLICATION OF LOW Pt CONTENT CATALYST FOR C8 AROMATICS ISOMERIZATION

Low Pt content SKI-110 catalyst，an ethylbenzene dealkylation C8 aromatics isomerization catalyst，developed by Research Institute of Petroleum Processing has been applied in a large integrated complex. The performance test results show that low Pt content SKI-110 catalyst exhibits good catalytic performance，the isomerization activity of para-xylene reaches 23.04%，the conversion of ethylbenzene reaches 70.40% and the xylene yield is up to 98.00%. Lower production cost for para-xylene and less energy consumption of the unit are achieved.
