RIC-200型C8芳烃异构化催化剂在国产化芳烃装置的工业应用

介绍了RIC-200型C8芳烃异构化催化剂在中国石化海南炼油化工有限公司600 kt/a对二甲苯大型国产化芳烃联合装置的工业应用情况。该芳烃联合装置全部采用国产化技术，RIC-200型催化剂首次应用在国产化异构化工艺中。工业应用结果表明：芳烃联合装置国产化工艺合理，RIC-200催化剂的异构化活性高，生成率为22..86％，乙苯转化率为27.40%，单程C8芳烃损失率为2.28％，表明RIC-200催化剂具有优良的活性和选择性，装置在110%的较高负荷下，可以满足多产对二甲苯的要求。

APPLICATION OF C8 AROMATIC ISOMARIZATION CATALYST RIC-200 IN DOMESTIC AROMATICS COMPLEX

The first industrial application of RIC-200 C8 aromatics isomerization catalyst in a 600 kt/a aromatics complex in Hainan petrochemical co. Ltd., SINOPEC was introduced. The complex adopts the domestic technologies. The industrial results indicate that the domestic technology of aromatic complex is successful. The energy consumpton is relatively low and RIC-200 catalyst performs a high activity and selectivity under the high load of 110%. The PX isomerization rate of RIC-200 is 22.86%, the ethylbenzene conversion rate is 27.40%, C8 aromatics loss in a singl-pass is 2.28%. It is concluded that the RIC-200 catalyst can satisfy the demand of maximum PX production for a PX complex.
