| Abstract: | To conversion of CH_ 4 and CO_ 2 to C_ 2 Hydrocarbons, a series of Mn-CaO catalysts were prepared using coprecipitation method and the catalytic performance were studied. CH_ 4 and CO_ 2 conversion increase With Mn content increase, while C_ 2 selectivity decreases. The best catalytic performance was obtained over the Mn-CaO catalyst with a Mn/Ca ratio of 1/1 and the maximum C_ 2 yield 3.0% was obtained over it. Effects of reaction temperature, CO_ 2 partial pressure on the catalytic performance of Mn-CaO(Mn/Ca1) were investigated. The change in reaction performance with time on stream was also studied. |
