Kinetics of catalytic oxidation of carbon monoxide and methane combustion over alumina supported Ga2O3, SnO2 or V2O5

Carbon monoxide oxidation and methane combustion were studied on Ga2O3, SnO2 or V2O5 supported on γ-Al2O3 catalysts under the stoichiometric conditions. It was found that the catalytic activity depends on the pretreatment conditions (oxygen or hydrogen atmosphere) of the catalyst. Detailed kinetic investigations allowed determination the reaction rates and adsorption coefficients of Langmuir-type equations in the case of catalysts pretreated under oxygen atmosphere and reaction conducted with oxygen excess.
