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.CH4 coupling in the presence of H2 has been investigated to evaluate the plasma reactor. In the reactor, flowing reactants run crisscross through the circular plasma zone between the two electrodes. No substantial amount of coke is observed on surface of the rotary multi-tip and fixed cylinder electrodes after a long time of the continuous reaction at about 40 V of supplied voltage under 20 kHz of pulse frequency discharge plasmas. The rotary multi-tip electrode process is possessed of higher CH4 conversion and higher C2 hydrocarbons single pass yield and higher energy efficiency than the plasma processes using fixed wire-plate electrodes under the same conditions.
