Methane conversion in gliding arc discharge plasma has been studied.The focus of this research is to develop a process of converting methane to C₂ hydrocarbons.The influences of CH₄ flow rate,input voltage and electrode gap on methane conversion were investigated.The results show that the apparent energy requirement(AER) is obviously increased by enhancing CH₄ flow rate.The conversion of methane is improved by adjusting input voltage or electrode gap.And when the input voltage or electrode gap is large,the yield for C₂ hydrocarbons decreases significantly.The unsaturated hydrocarbons are the main products of C₂ hydrocarbons.Optimum conditions for producing C₂ hydrocarbons from methane are suggested.A maximum methane conversion of 43.1% is obtained under the optimum conditions.Also,the selectivity and yield for C₂ hydrocarbons and AER are 40.1%,93.2% and 2.41 MJ/mol,respectively.
