摘　　要：担载型过渡金属催化剂上甲烷直接转化为低碳烃的研究阎子峰＊薛锦珍沈师孔＊＊王弘立（中国科学院兰州化学物理研究所羰基合成与选择氧化国家重点实验室，兰州７３００００）关键词甲烷，同系化反应，低碳烃，过渡金属，担载型催化剂，瞬变应答反应近十年来，甲烷氧化偶联...The homologation of methane on supported transition metal catalysts was investigated by means of transient response reaction. The different factors which strongly affected the reaction were also studied. An important approach is to split the overall reaction into two reaction steps occurring under moderate conditions. In such a two step route, the thermodynamic limitations can be overcome and the homologation of methane may be practically achieved. The optimum conversion of methane on 5%Pt/SiO 2 catalyst is 9 91% (at 523 K).
