The effect of sulfur on deactivation of palladium catalysts for methane oxidation has been investigated in this research. A PdO deactivation mechanism due to sulfur is proposed over the 100–400°C range. H2S induced catalyst poisoning of PdO/γ–Al2O3 is attributed to the formation of aluminum sulfate....
