Numerical Simulation of NO/NO2/NH3 Reactions on SCR-Catalytic Converters:Model Development and Applications

Abstract
A 1D+1D numerical model describing the ammonia based SCR process of NO and NO₂ on vanadia-titania catalysts is presented. The model is able to simulate coated and extruded monoliths. Basing on a fundamental investigation of the catalytic processes a reaction mechanism for the NO/NO₂ - NH₃ reacting
