| 中文摘要: |
| 用浸渍法制备了一系列的Ｎｉ－Ｒｕ稀土／ＺｒＯ_２三组份担载型二氧化碳甲烷化催化剂，并利用固定床反应器对其催化性能进行了研究。实验结果表明，添加稀土后的三组份催化剂具有较高的催化活性，含稀土催化剂的活性与稀土离子的４ｆ电子数有关，稀土元素的磁性对催化剂性能有一定影响，不同催化剂的反应表观活化能大小次序与催化剂活性次序相符。 |
| 英文摘要: |
| in this paper,rare earth containing three-component catalysts supported on zirconia are prepared by impregnation.Catalytic investigations are carried out with a fix bed microreactor. The catalysts show high activity for the methanation of carbon dioxide at high space velocity and ordinary pressure.They can convert carbon dioxide to methane almost entirely at 673 K. Results also indicate that there are some relationships between catalytic activity and magnetic property of the rare earth. |
