新型C_8芳烃异构化催化剂性能考察

STUDY ON PERFORMANCE OF NEW C_8 AROMATICS ISOMERIZATION CATALYST

在实验室考察了新型C8芳烃异构化催化剂RIC-200的性能随工艺条件变化的规律,并在工业装置上与SKI-400催化剂的性能进行对比。结果表明:工业装置上RIC-200催化剂的性能随工艺条件变化的趋势符合实验室研究的规律;具有提温速率慢、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、氢烃比低和氢耗低、C8芳烃收率稳定的特点。新型RIC-200催化剂对工艺条件的适应性好。

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 molar ratio,low hydrogen consumption,and stable C8 aromatics yield.The RIC-200 catalyst also demonstrates its excellent adaptability in varying industrial operation conditions.
