Abstract
The oxidative conversion of methane was studied over lead containing zeolites of type X, silicalite and ALPO-5 in the temperature range 750-850 °C. An impregnation of catalysts in the range 3-7 wt.% lead was found optimum for the conversion and C2 selectivity. The 6.4 wt.% 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.This publication has 0 references indexed in Scilit:
