采用水溶液浸渍法制备一系列无机氧化物 (SiO2 、α—Al2 O3、γ—Al2 O3、ZrO2 )担载的Ⅷ族金属 (Fe、Co、Ni、Cu)催化剂 .研究了它们在CO2甲烷化反应中的催化性能 .结果表明 ,催化剂性能与金属本性有关 .Ni在各种载体上均具有较高活性 ,Fe的活性较低 ,而Cu基本上无活性 .Mn作为双金属成分添加在Ni基催化剂中可提高CO2 的转化率 .而且 ,3%Ce— 6 %Ni— 6 %Mn α—Al2 O3催化剂在反应中表现出很高的催化活性 A series of Fe, Co, Ni and Cu supported on inorganic oxides (SiO2, α-Al2 O3, γ-Al2 O3, ZrO2) were prepared by impregnation with aqueous solution. .The results show that the catalyst performance is related to the nature of the metal.Ni has higher activity on various carriers, Fe activity is lower, while Cu is basically inactive.Mn as a bimetallic component added to the Ni-based catalyst Can increase the CO2 conversion rate.Moreover, the 3% Ce- 6% Ni- 6% Mn α-Al 2 O 3 catalyst shows high catalytic activity in the reaction
