Abstract: | The selective catalytic reduction (SCR) of NO by propane in excess oxygen-containing gas mixture was studied on Co/Al2O3 catalyst. The oxygen concentration is very important for the reaction. The NO conversion to N2 without oxygen is 3% at 800 K and when the O2 concentration is raised up to 8% the NO conversion reaches its maximum value of 60% at 800 K. Characterization results by
TPR and UV-Vis spectroscopy show that in the catalyst, species strongly interacting with tetrahedral and octahedral Co2+ ions in the support are present.
