Pt-Pd /y-A120.催化剂氧化性能的研究‘

本文采用浸演法制备了一系列Pt-Pd/Y-AlzO,催化剂，并考察其对正己烷，正丁醉和苯的催化氧化性能.结果表明，Pt-Pd双组分催化剂对极性有机物正丁醉有很高的氧化活性，而对于非极性有机物苯和正己烷的氧化活性相对较差.对Y-AlzOa载体进行高温预处理后，催化剂对苯和正己烷的氧化活性有明显提高.

An Investigation on the Oxidation Activity of Pt-Pd/Y-A1203 Catalyst

In this paper, a series of Pt-Pd/Y-AlzOs catalysts have been prepared by impregnation method.Their catalytic activities for oxidation of n-hexane，n-butanol and benzene have been investigated. Thereults indicated that activities of the catalysts for n-butand oxidation were very high, while that for n-hexane and benzne oxidation were relatively poor. Calcination of Pt-Pd/1'-A1z03 at high temperaturecould evidently increase the activities of the catalysts for benzene and n-hexane oxidation.
