Abstract
An experimental investigation on oxidative synthesis of ethane and ethylene from CH4 using CO2 as an oxidant has been performed by streamer discharge reactions, which are initiated by an AC electric field. This gas discharge promotes the methane conversion to reach a high yield of C2 hydrocarbons of 20%∼45% with a methane conversion of 25%∼80% and a conversion of carbon dioxide of 8%∼40%. The reactions for these conversions are: 2CH4 + CO2 → C2H6 + CO + H2O and 2CH4 + 2CO2 → C2H4 + 2CO + 2 H2O. A possible pathway of C2 formation was also present in this letter.
