Methane coupling to produce C2 hydrocarbons was studied with a newly developed rotary helix electrode in glow discharge plasma at atmospheric pressure.

A novel plasma reactor with rotary multi tip electrode and a fixed concentric cylinder electrode has been developed in order to use in CH4 discharge and to produce unsaturated C2 hydrocarbons.

Investigation results showed that in pure methane gas,methane was mainly converted to C2 hydrocarbons; in pure ethane gas, converted to C2H2 and C2H4.

Process of methane decomposition and C_2 hydrocarbons formation in DC discharge plasma were investigated by measuring IR emission spectrum.

Low-power catalytic conversion of methane to C_2 hydrocarbons (ethane, ethylene and acetylene) through AC or DC plasma catalysis reactions in symmetric electrical field was studied under low temperature and atmospheric pressure.

The direct conversion of methane coupling to C 2 hydrocarbon is the natural way of obtaining its reasonable usage.

Clean and direct conversion of methane to C 2 hydrocarbons (ethane, ethene and acetylene) through AC and DC plasma catalysis enhanced by electric field was studied at low temperature ranging from 50?℃ to 100?℃, atmospheric pressure and low power conditions.
