| 摘 要： | 本文主要运用ＳＥＭ、ＥＤ５、ＸＲＤ、ＡＡＳ等技术，研究了新鲜的和失活的第二代临氢脱烷基制苯催化剂（Ｃｒ＿２Ｏ＿３－ＮｉＯ－ＣｅＯ＿２／γ－Ａｌ＿２Ｏ＿３）的表面形态和活性组份分布的差异；从实验和理论两方面入手，探讨了这种催化剂在实际工业生产中容易引起飞温失活的可能原因。

| Abstract: | This paper investigates the difference in morphological structure and active componentsdistribution between fresh and used Cr_2O_3-NiO-MgO-CeO_2/r-Al_2O_3 catalysts by SEM, EDS,XRD,and AAS.Deactivation of used industrial catalysts is caused by the change in morphological structure and active components distribution. |
