| Abstract: | The pulse corona plasma has been used as an activation method for reaction of methane and carbon dioxide, the product was C2 hydrocarbons and by-products were CO and H2. Methane conversion and the yield of C2 hydrocarbons 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 C2 hydrocarbons decreased. The synergism of La2O3/γ-Al2O3 and plasma gave methane conversion of 24.9% and C2 hydrocarbons yield of 18.1% were obtained at the power input of plasma was 30 W. The distribution of C2 hydrocarbons changed by using Pd-La2O3/γ-Al2O3 catalyst, the major C2 product was ethylene. |
