摘　　要：考察了不同组成MnCaO催化剂上甲烷二氧化碳转化制C2烃反应性能,同时考察了反应温度,CO2分压对反应性能的影响及催化反应性能随时间的变化.To conversion of CH4 and CO2 to C2 Hydrocarbons, a series of Mn-CaO catalysts were preparec using coprecipitation method and the catalytic performance were studied. CH4 and CO2 conversion increase With Mn content increase, while C2 selectivity decreases. The best catalytic performance was obtained over the Mn-CaO catalyst with a Mn/Ca ratio of 1/1 and the maximum C2 yield 3.0% was obtained over it. Effects of reaction temperature, CO2 partial pressure on the catalytic performance of Mn-CaO（Mn/Ca=1） were investigated. The change in reaction performance with time on stream was also studied.
