Reaction Pathways in the Selective Catalytic Reduction Process with NO and NO2 at Low Temperatures
TL;DR: The low-temperature behavior of the selective catalytic reduction (SCR) process with feed gases containing both NO and NO2 was investigated in this article, where the two main reactions are 4NH3 + 2NO + 2 NO2 → 4N2 + 6H2O and 2NH3+ 2NO2 → NH4NO3 + N2 + H2O.
Journal ArticleDOI
Selective catalytic reduction of NO and NO2 at low temperatures
TL;DR: In this paper, the authors investigated the effect of ammonium nitrate on the SCR reaction in the presence of NO and showed that ammonium Nitrate can lead to the formation of NO 2.
Journal ArticleDOI
Enhanced reoxidation of vanadia by NO2 in the fast SCR reaction
TL;DR: In this paper, the authors investigated the role of NO2 on catalysts based on TiO2-WO3-V2O5 and showed that the vanadium species formed during the reduction of NO with ammonia are reoxidized faster by NO2 than by oxygen, resulting in an increased reaction rate of the fast SCR reaction.
Journal ArticleDOI
Thermal stability of vanadia-tungsta-titania catalysts in the SCR process
TL;DR: The thermal behavior of TiO 2 -WO 3 -V 2 O 5 catalysts with various vanadia contents was investigated using X-ray diffraction (XRD), XPS, Raman spectroscopy and BET surface area determination.
Journal ArticleDOI
Side Reactions in the Selective Catalytic Reduction of NOx with Various NO2 Fractions
TL;DR: In this paper, the main and side reactions of the three selective catalytic reduction (SCR) reactions with ammonia over TiO2−WO3−V2O5 catalysts have been investigated using synthetic gas mixtures matching the composition of diesel exhaust.
