摘　　要：研究了用于甲醇部分氧化制氢气反应的Ag/CeO2-ZnO催化剂的制备条件以及反应条件对催化剂性能的影响。Ag/CeO2-ZnO催化剂中银含量、焙烧温度、反应温度以及反应气的比例等对催化剂性能具有很大的影响。Ag/CeO2-ZnO催化剂的制备条件以及反应条件控制在一定范围内时,Ag/CeO2-ZnO催化剂对甲醇部分氧化制氢气具有很高的催化活性与选择性。The preparation of Ag/CeO2 -ZnO catalyst used for preparing hydrogen from methanol by partial oxidation and the effect of reaction conditions of the process on the catalytic performance are studied. It is found that the loading of Ag in the catalyst,the calcinating and reaction temperature and the ratio of reaction gases have a significant effect on the catalyst performance. When the preparation conditions of the catalyst and the reaction conditions of the process are controlled within a certain scope, the Ag/CeO2 - ZnO catalyst used for the preparation of hydrogen from methanol by partial oxidation has high catalytic activity and selectivity.
