Synthesis and Characterization of Pt/Al_2O_3 Catalyst for Methane Partial Oxidation System Synthetic gas

Chen Guo

Abstract

In the present work,three Pt/Al2O3 catalysts were synthesized by the impregnation method for the oxidation selectivities of the catalysts.The temperature programmed reduction,temperature programmed desorption and the technology of micro-pulse were used to investigate the characteristics of the catalysts.As a result,we observe that the oxidation characteristic of the catalyst increases as the amount of the Pt increases.In addition,at the 4wt%Pt/Al2O3,and the ratio of the feed gas is CH4/O2=2∶1,the conversation of the methane reaches nearly 98%.
