摘要/Abstract

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、H₂O、CO₂和H₂在Cu/ZnO/A1₂O₃型低变催化剂上的吸-脱附行为,并对与Cu/ZnO/A1₂O₃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/A1₂O₃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。

Abstract: The adsorption and desorption of CO, H₂O(g), CO₂ and H₂ in the water gas shift reaction on the Cu/ZnO/Al₂O₃ catalyst were studied by TPD. And a similar discussion was made for six samples which bore analogy definite to Cu/ZnO/ A1₂O₃ catalyst. It was discovered through analyzing qualitativly to TPDspectra had been got that the adsorption and desorption action were different for the water gas shift reaction conponents on the compositions of Cu/ZnO/Al₂O₃.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.
