REACTION MECHANISM AND MICRO-KINETIC MODEL FOR NH3-SCR OF NO AND NO2 ON V2O5/TIO2-WO3 CATALYST
Background Nitrogen oxides (NOx) are formed in combustion and have been removed efficiently by NH3- and urea- SCR methods in stationary since 1970s and mobile applications more widely since 2005. Urea is used a source of ammonia (NH3) in mobile applications. The main reactions are known as standard (NO only) and fast (NO2 present) SCR reactions, which were proposed earlier. Few reaction studies have been published about the role of NO2 to promote SCR. However, the current study will present the complete surface reaction paths, where kinetic model and simulations were based.
