Abstract: The IR emission spectra of methane were measured under DC glow discharge conditions. The
distinct difference in time between methane decomposition and C2 hydrocarbons formation was
specially pointed out. C2hydrocarbons formed at the end of methane decomposition. The
optimum condition for C2 hydrocarbon formation was studied and the optimum combination
between electric current density and methane input quantity was suggested. The appropriate
reaction conditions for methane decomposition and C2 hydrocarbons formation are different,
so high yield of C2 hydrocarbons will be probably obtained when different conditions are
taken.
