The reaction conditions of reaction of ethane with carbon dioxide were optimized, and the effect of reaction conditions on the properties of ethylene with K Fe Mn / Si 2 catalyst was investigated. The effect of reaction conditions on the properties of ethylene at 80 ℃, 0 1MPa, 100h-1, K 2 Mn / Si 2 and K Cr Mn / Si 2 catalysts were investigated under the reaction conditions of V (CO 2) / V (H 2 O) = 1/1 / 2 catalyst has good reaction stability between ethane and carbon dioxide, and the reaction stability of K Cr Mn / Si 2 catalyst is poor. By investigating the catalyst regeneration performance, it is found that K Fe Mn / Si 2 catalyst has good regeneration performance , While the deposited K Cr Mn / Si 2 catalyst is more difficult to regenerate.
