SKI-110型C8芳烃异构化催化剂的工业应用

介绍了石油化工科学研究院新开发的SKI-110乙苯脱乙基类型的C8芳烃异构化催化剂在大型工业装置中应用的情况。结果表明，SKI-110型催化剂的活性和选择性良好，二甲苯异构化活性达到23.41%，乙苯转化率达到59.18%，单程二甲苯损失1.54%，达到预期值，满足优化产品结构、降低对二甲苯生产成本、控制联合装置操作能耗等方面的使用需求。

COMMERCIAL APPLICATION OF SKI-110 CATALYST FOR C8 AROMATICS ISOMERIZATION

SKI-110 catalyst, an ethylbenzene dealkylation C8 aromatics isomerization catalyst, newly developed by Research Institute of Petroleum Processing was applied in a large integrated complex. The performance test results showed that SKI-110 catalyst exhibited good catalytic performance, the isomerization activity of xylene reached 23.41%, the conversion of ethylbenzene reached 59.18% and the xylene loss was 1.54%, which well met the expected targets. Optimized product distributions, lower para-xylene product cost and less energy consumption of the unit were achieved.
