| 中文摘要: |
| 用浸渍法制备了铝钛复合载体担载的钌催化剂，考察了它们对二氧化碳甲烷化反应的催化性能，结果表明，高TiO2含量载体制备的催化剂的活性和选择性较高，同时考察了反应温度、空速、金属担载量以及添加第二金属组分等对催化剂性能的影响． |
| 英文摘要: |
| Ru Catalysts supported on Al-Ti mixed oxides were prepared by impregnation method. Their catalytic activities for the methanation of carbon dioxide were investigated. The results showed that their catalytic activities were influenced by the content of TiO_2 in the supports. Both the conversion of carbon dioxide and selectivity of methane strongly depended on the reaction conditions. Their catalytic activities were enhanced by the increase of reaction temperature in the range of 473 K~773 K and metal content of Ru in 0.3%~1.0%. The introductions of other metals affected their catalytic activities too. |
