采用脉冲电晕等离子体作为甲烷和二氧化碳反应的活化方法，产物为C2烃，副产物为CO和H2。进料中二氧化碳浓度对甲烷转化率和C2烃的产率有影响。随着进料中二氧化碳浓度的增加，甲烷转化率增加，而C2烃的产率下降。在La_2O_3/γ-Al_2O_3与等离子体的协同作用下，当等离子体功率为30W时，甲烷转化率为24.9%，C_2烃产率为18.1%。Pd-La_2O_3/γ-Al_2O_3催化剂改变了C_2烃的分布，主要C_2产物为乙烯。
The pulse corona plasma has been used as an activation method for reaction of methane and carbon dioxide, the product was C2hydrocarbons and by-products were CO and H2. Methane conversion and the yield of C2hydrocarbons were affected by the carbon dioxide concentration in the feed. The conversion of methane increased with increasing carbon dioxide concentration in the feed whereas the yield of C2hydrocarbons decreased. The synergism of La2O3/γ-Al2O3and plasma gave methane conversion of 24.9% and C2hydrocarbons yield of 18.1% were obtained at the power input of plasma was 30W. The distribution of C2hydrocarbons changed by using Pd-La2O3/γ-Al2O3catalyst, the major C2product was ethylene.
