摘　　要：采用新型多尖端旋转电极,通过改变反应物流率和输入功率,考察了甲烷在常压辉光等离子体中偶联反应的转化率、C2烃的收率、C2烃的选择性、空时能量密度、能量效率和放电功率的变化。结果表明,当输入功率为84W、甲烷与氢气的流率为20ml/min时,甲烷的转化率为74 2%,相应的C2烃收率为70 7%,C2烃选择性为95 3%。Coupling of methane was carried out in a glow-discharge reactor with a rotating poly-tip electrodes operated under atmospheric pressure.Flow rate of reactants and input power were correspondingly changed in order to investigate how methane conversion,C2 hydrocarbon yield,C2 hydrocarbon selectivity,space-time energy density,energy efficiency and discharge power were influenced by these two varying factors.Methane conversion attained 742%,with 707% C2 hydrocarbon yield and 953% C2 hydrocarbon selectivity when the flow rate of reactants are 20 ml/min and input power of 84 W.
