CH_4/CO_2一步合成C_2烃研究进展

Recent progress in synthesis of C_2 hydrocarbons from CH_4/CO_2

介绍了CH4 /CO2 一步合成C2 烃的两条主要途径 :化学催化法和等离子体活化法。化学催化法主要采用金属氧化物催化剂及负载型金属氧化物催化剂 ,后者的催化活性明显高于前者 ,是今后化学催化法的研究方向。冷等离子体是十分有效的自由基引发方式 ,在此反应中的应用获得了比化学催化法更高的C2 烃收率。CH4 /CO2 一步制C2 烃是一条合成路线简单、原料廉价易得的崭新合成路线 ,有望成为CH4 /CO2 合成C2

Two new routes of synthesis are reviewed for producing C 2 hydrocarbons from CH 4/CO 2. One is chemical catalyst and the other is plasma activation.Metal oxide and supported metal oxide are used as catalysts in chemical catalytic method.The catalytic activity of latter is higher than former.Cold plasma is a kind of effective method to produce free radicals,so it can be obtained higher C 2 yield than chemical catalyst by plasma way.Adopting the route to direct synthesize C 2 hydrocarbons from CH 4/CO 2 is expected to make greate progress because it simple and cheap.
