The effects of HCl, H2S, tributyl phosphate (TBP), P2O5, and zinc dialkyldithophosphate (ZDP) as catalyst poisons for methane oxidation over palladium catalysts supported on γ-alumina were investigated in this study. The overall reaction rate of methane oxidation over palladium catalysts can be simplified into a pseudo first order reaction under excess oxidation conditions.
The deactivation of the catalyst poisoned by HCl is attributed to the loss of active sites due to volatilization of PdCl2. H2 treatment at 200 °C can reactivate the catalyst poisoned by HCl at temperatures of up to …
