The model fits well the experimental data of oxidation of NO as well as reduction of NO to N2. Remarkable differences have been found in performance of Cu-MFI and Fe-MFI catalysts. While Fe-MFI is more active in oxidation of NO to NO2, Cu-MFI exhibits much higher activity in the reduction of NO with decane. The kinetic model indicates that the significantly lower activity of Fe-MFI in comparison with Cu-MFI in transformation of NOx to nitrogen is due to higher rate of transformation of NO2, formed in the first step by the oxidation of NO, back to NO instead to molecular nitrogen.
