Catalytic performances of lead oxide supported on MgO which has been discovered to exhibit excellent characteristics for the oxidative coupling of methane to C/sub 2/ hydrocarbons have been studied. A 20 wt % PbO/MgO catalyst gave 13% methane conversion, 98% oxygen conversion, and 71% C/sub 2/ selectivity at 800/sup 0/C, a time factor of 1.0 g . h/mol, a feed gas composition for CH/sub 4/ of 14% and for O/sub 2/ of 1.6%, and atmospheric pressure. Significant changes of catalyst performance were observed with time. The methane conversion rate and C/sub 2/ selectivity as a function of PbO loading were examined to clarify that 5 wt % PbO loading was the best. It was also clarified that ethylene and carbon dioxide were made successively from ethane and carbon monoxide, respectively.
