The oxidative conversion of methane was studied over lead containing zeolites of type X, silicalite and ALPO-5 in the temperature range 750 - 850 deg C.An impregnation of catalysts in the range 3 - 7 wt.percent lead was found optimum for the conversion and C2 selectivity.The 6.4 wt.percent lead-containing zeolite showed the best C2 hydrocarbon yield.Higher reaction temperatures caused higher C2H4/C2H6 ratios.The catalysts did not deactivate in 10 h time-on-stream.PbO and zeolitic basic sites play role in the reaction.
