担载型钅了催化剂对二氧化碳甲烷化的催化性能

采用水溶液浸渍法制备了多种无机氧化物担载的钅了催化剂，并对其在二氧化碳甲烷化反应中的催化性能作了研究。结果表明，无机氧化物担载的钅了催化剂具有高活性；不同载体担载的体系有如下的活性次序：ＴｉＯ２＞ＺｒＯ２＞海泡石＞Ａｌ２Ｏ３＞ＳｉＯ２；反应条件及第二组份的添加对催化性能均有影响；催化剂作用下的反应活化能大小顺序与活性变化规律相符

THE CATALYTIC ACTIVITY OF SUPPORTED Ru CATALYST FOR THE METHANATION OF CO 2

Some Ru catalysts supported on inorganic oxides have heen prepared by aqueous impregnation, their catalytic activities are investigated. The results indicate that Ru catalysts supported on inorganic oxides show their high activities, that the catalytic activities of catalysts louded on different supports follow the following active order: TiO 2>ZrO 2>sepiolite>Al 2O 3>SiO 2,that reaction conditions and the additions of second componental metals influence the catalytic activities, and that the sequence of activation energy by the action of catalysts coincide with the law of activation.
