摘 要: | It has been reported that methane coupling by plasma techniques with catalysts, such as direct current corona discharge with a Sr/La2O3 catalyst[1], dielectric-barrier discharge with zeolites[2] and pulsed corona discharge with metal oxide catalysts[3], give C2 hydrocarbons under atmospheric pressure. But acetylene predominates over other C2 hydrocarbons in the products. Our recent work reported that good results can be obtained for methane coupling under a pulsed corona plasma in the presence of hydrogen[4]. The addition of hydrogen improves the conversion of methane and the yield of C2 hydrocarbons. A methane conversion of 57.1% and a yield of C2 hydrocarbons of 43.4% were obtained at lower power, but acetylene was inevitably the main product. With the introduction of a Ni/γ-Al2O3 catalyst prepared by a cold plasma into the plasma reaction, the distribution of C2 hydrocarbons changed, and the content of C2H4 was 66.1%[5].
