摘    要:采用浸渍-还原和浸渍-焙烧-还原两种方法制备了Fe/TiO2和Ni/MgO/Al2O3催化剂,分别比较了它们在CO2加氢制低碳烃、CO2与CH4重整制合成气反应中的催化活性,结果表明:与浸渍-焙烧-还原相比,浸渍-还原制备的催化剂显示出更好的催化活性,基于对催化剂表面结构的认识,提出催化剂还原过程的表面结构模型,并解释了制备方法对催化剂反应活性的影响长质。

关 键 词:制备方法  催化活性  表面结构模型  CO2活化

Abstract:Fe/TiO 2 and 5% Ni/MgO/Al 2O 3 catalysts are prepared by impregnation reduction and impregnation calcination reduction methods and evaluated the catalytic activity in carbon dioxide hydrogenation to low hydrocarbons and carbon dioxide reforming of methane to synthesis gas, respectively. The catalyst prepared by impregnation reduction method has higher catalytic activity than the one prepared by impregnation calcination reduction method. Based on comprehension of surface structure of the catalysts, it is suggested a surface structure model to explain the fact.
Keywords:preparation method  catalytic activity  surface structure model  CO  2 activation
