Plasma chemical conversion of methane in the presence of water

The conversion of methane into gaseous and liquid products in a dielectric barrier discharge plasma in the presence of water are studied. The formation of a deposit on the electrode surface is prevented by introducing water in the liquid state into a gaseous methane stream. Hydrogen and C2+ hydrocarbons are identified among the gaseous products of conversion, the liquid products being represented by C6–C10+ alkanes. The total of liquid products has amounted to 13.4%. The model of chemical kinetics of the conversion of methane in the dielectric barrier discharge in the presence of water is proposed. The results of the simulation are presented.
