新型C8芳烃异构化催化剂性能考察

介绍了新型C8芳烃异构化催化剂RIC-200的实验室和工业应用情况，并与SKI-400催化剂进行对比。工业应用结果表明：RIC-200催化剂的性能随工艺条件变化的趋势符合实验室规律；具有提温速度慢、反应压力升高不仅可以使乙苯转化率增加同时也可以使异构化活性增强、氢烃摩尔比低和氢耗少、C8芳烃收率稳定的特点。新型RIC-200催化剂的工艺条件适应性好。

STUDY ON PERFORMANCE OF NEW C8 AROMATICS ISOMERIZATION CATALYST

This paper introduces the performance of a new C8 aromatics isomerization catalyst RIC-200 in laboratory and commercial unit, and compares with the results of SKI-400 catalyst under the industrial conditions. The results of the new catalyst indicate that the performance of RIC-200 under industrial operation conditions is in accordant with the results in laboratory test and better than SKI-400. The new catalyst possesses distinct characteristics，such as low deactivation rate,high ethylbenzene conversion and enhanced isomerization activity under even high pressure, low H2/HC, low hydrogen consumption, and stable C8 aromatics yield. The RIC-200 catalyst also demonstrates its excellent adaptability in varying industrial operation conditions.
