The microwave plasma and catalytic reaction have been employed to investigate the activation of methane to hydrogen and higher hydrocarbons at low gas temperature. The catalytic activity of Fe, Ni, Pt Pd metal catalysts were also studied in this reaction system. With increasing plasma power at a $CH_{4}$ flow rate of 20 ml/min, C2+ products increased from 29 to $42\%$, whereas hydrogen from 60 to $65\%$. When catalysts were loaded below the plasma region, the selectivitity of ethylene md acetylene increased but the yield of C2+ products remained constant. The usage of ECR electric fie3d and Pd-Ni bimetal catalyst produced a minimum C2+ yield of $64\%$.
