Modification of La on Co/γ-Al_2O_3 Catalyst for Selective Hydrogenation

Peng‐Mian Huang, Zili Liu

Abstract

The reasons of Co-La/γ-Al_(2)O_(3)activity improved by La were investigated using XPS,TG,DTA and XRD techniques.With the addition of La XPS characterization indicated the Co2p content on the catalysts surface was 1.65 times than before.The DTG and TDA result showed that the weight loss temperature and thermostability were changed little.The XRD result indicated that the catalysts dispersity was improved.
