Kinetics of NH3-SCR Reactions Over V2O5–WO3/TiO2 Catalyst

Abstract

An extensive investigation of the chemistry, the mechanism, and the kinetics of the NO-NO2/NH3 SCR reactions for mobile applications was performed over a commercial vanadium-based catalyst. On the basis of the collected results, a Mars-Van Krevelen dynamic kinetic model was derived, which unifies the rates of the Standard and the Fast SCR into a single Redox-type approach.
