Abstract

Conversion of methane to C2, C3, C4 or higher hydrocarbons in a dielectric-barrier discharge was studied at atmospheric pressure. Non-equilibrium plasma was generated in the dielectric-barrier reactor. The effects of applied voltage on methane conversion, as well as selectivities and yields of products were studied. Methane conversion was increased with increasing the applied voltage. Ethane and propane were the main products in a dielectric-barrier discharge at atmospheric pressure. The reaction pathway of the methane conversion in the dielectric-barrier discharge was proposed. The proposed reaction pathways are important because they will give more insight into the application of methane coupling in a DBD at atmospheric pressure.
