Study on Coupling of Methane in Glow-discharge Reactor with Rotating poly-tip Electrodes*

Coupling of methane in the present of hydrogen to C2hydrocarbons operated at atmospheric pressure in order to evaluate a newly-developed plasma reactor with rotating poly-tip electrodes, in which circular glow discharge plasma zone between a stator and a rotor with polytip electrodes is vertical to the way of the stream of flowing reactants. No substantial amount of carbon formation was observed on the surface of the electrodes after a long period of the reaction(>1 h) when the molar ratio of feed flow of CH4∶H2is 1∶1 and the A.C. glow discharge at 20kHz, input power of 856 V(rms). C2hydrocarbons single pass yield is 42.6%, in which C2H2 38.9% and C2H43.5% respectively, with 62.3% methane conversion but with carbon formation when input power is 1010 V(rms)
