Detailed kinetic modeling of NOx adsorption and NO oxidation over Cu-ZSM-5

Abstract. Detailed kinetic modeling was used in combination with flow reactor experiments to investigate the NOx adsorption/desorption and NO oxidation over Cu-ZSM-5. NO oxidation is likely an important step for selective catalytic reduction (SCR) using urea and hydrocarbons, and thus was investigated separately. First the NO2 adsorption on Bro¨ nstedt acid sites in H-ZSM-5 was modeled usi…
