【Abstract】 The preparing process of copper-manganese oxide catalyst for water gas shift is further studied. The effects Of oxidizability, the adding amount of promoter and the proportion between the promoters on the characteristics of the catalyst are investigated. The experimental results indicate that the copper-manganese oxide appears in an optimal oxidizability, and during this state,the activity and the thermal stability of catalyst reach an optimum value. The preparing process is simple and the product is washed easily. The different points of view on the crystal structure of the copper-manganese Oboe are clarified.更多还原
