| Abstract: | The effects of various metal oxides on the crystal structure and chemical characteristics of an iron chromium catalyst are researched by the temperature programmed reduction(TPR)technique, X ray analysis and catalytic activity test. The results show that CeO 2 on the surface of Fe 2O 3 can improve activity of the iron chromium catalyst and that Bi 2O 3 can get into the interior of Fe 2O 3, improve CO conversion rate and enhance the stability of the catalyst. |
