摘　　要：本文采用程序升温脱附法(TPD)研究了低变反应各组分CO、H_(2)O、CO_(2)和H_(2)在Cu/ZnO/Al_(2)O_(3)型低变催化剂上的吸-脱附行为,并对与Cu/ZnO/Al_(2)O_(3)具有可此相对组成的六种样品进行了类似的讨论,通过对所得TPD谱图的定性分析发现:构成Cu/ZnO/Al_(2)O_(3)型低变催化剂的各个组元对低变反应各组分的吸-脱附作用互不相同,且不同的组元具有各自的吸-脱附特征。The adsorption and desorption of CO, H_(2)O(g), CO_(2) and H_(2) in the water gas shift reaction on the Cu/ZnO/Al_(2)O_(3) catalyst were studied by TPD. And a similar discussion was made for six samples which bore analogy definite to Cu/ZnO/ Al_(2)O_(3) catalyst. It was discovered through analyzing qualitativly to TPD spectra had been got that the adsorption and desorption action were different for the water gas shift reaction conponents on the compositions of Cu/ZnO/Al_(2)O_(3). Different compositions had an adsorption and desorption characteristic in itself. All the results gave useful informations for an explanation of the mechanism of the low temperature water gas shift reaction.
