Abstract
This paper presents results which were obtained for the flameless combustion of methane over the Pd(PdO)/Al 2O 3 catalyst by using the steady state isotopic transient kinetic analysis method. During the reaction switches between 16O 2/Ar/CH 4/He and 18O 2/CH 4/He were carried out. The obtained results indicate the presence of large amounts of oxygen as well as of intermediates leading to the formation of carbon dioxide on the surface of the palladium catalyst. Additionally, information was obtained proving that the complete oxidation of methane over Pd/Al 2O 3 catalyst proceeds according to the Mars and van Krevelen redox mechanism. With the increase of the reaction temperature there is an increase in the number of active centres on the Pd(PdO)/Al 2O 3 catalyst surface—a larger amount of oxygen from the lattice of the catalyst is accessible for the reaction of methane oxidation.
