In the reaction of methane and carbon dioxide to C₂ hydrocarbons under non-equilibrium plasma, methane conversion was decreased, but selectivity of C₂ hydrocarbons was increased when using La₂O₃/γ-Al₂O₃ as catalyst.So the yield of C₂ hydrocarbons was higher than using plasma alone.The synergism of La₂O₃/γ-Al₂O₃ and plasma gave methane conversion of 24.9% and C₂ yield of 18.1%.The distribution of C₂ hydrocarbons changed when Pd-La₂O₃/γ-Al₂O₃ was used as catalyst, the major C₂ product was ethylene.
