CATALYTIC PERFORMANCE AND CHARACTERIZATION OF A NEW TYPE C 8 ARENE ISOMERIZATION CATALYST

本文报道一种新型Ｃ８芳烃异构化催化剂的性能，这种催化剂是由低结晶度的氢型丝光沸石负载金属铂制得，它具有载铂量低（０．１％Ｗｔ左右），不外加任何载体、制备工艺简单的特点；用脉冲微反、常压、高压连续微反装置对催化剂的活性、选择性、稳定性进行了考察，用ＮＨ３－ＴＰＤ、Ｐｙ－ＩＲ。

A new type C 8 arene isomerization catalyst was prepared by the lower crystallinity′s H mordenite loading with Pt.Its character is low Pt content (about 0.1%wt), support unnecessary and simple preparatively.The catalytic activity,selectivity and stability have been investigated by the micro reactor.The catalyst was characterized through NH 3 TPD,Py IR and TEM.
