Plasma methane conversion using gliding arc discharges

The methane transformation into C2 hydrocarbons was studied under plasma conditions using a new developed laboratory gliding arc (Glid-Arc) reactor operated at the frequency of 50 Hz. The methane processing was carried out in gas mixtures CH4+H2 and acetylene was found to be the main product with a small amount of ethylene. The overall methane conversion ranging from 25 to 36% was obtained and the selectivity of methane conversion to acetylene was generally high.
