These results clearly demonstrate a synergetic effect of H2 and NH3 in the N Ox reduction on the W-promoted catalyst. Moreover, it is apparent that the lower N2O formation in the H2-deNOx reaction on Pt/11W/AlSi-20 (Fig. 11) coincides with the diminished N2O ...
Pt catalystKinetic modellingThermodynamic consistencyThis paper addresses the elementary kinetic mean field modelling of the NOx reduction by H2 on Pt/WO3/ZrO2 under oxygen-rich conditions. Pt/WO3/ZrO2 was recently shown to reveal substantial low-temperature deNOx activity with enhanced N2 selectivity ...

Thus, the aim of this paper is the development of a H2-deNOx catalyst with pronounced low-temperature activity and minimum N2O production, whereas the present study mainly focuses on diesel exhaust. For this purpose, a series of Pt/ZrO2 and Pt/WO3/ZrO2 samples was systematically prepared, ...

Additionally, factors\ninhibiting the H2-deNOx reaction, such as high CO/ HC contents, were identified and\neliminated where possible. From laboratory data using a 1″x2″ honeycomb catalyst, a\nstatistical model was developed to approximate NOx conversion and N_2O formation\nunder boundary ...

Ag/Al2O3 with higher silver loadings exhibited better deNOx performance and sulfur tolerance, especially the 4% Ag/Al2O3 catalyst. UV-vis and H2-TPR revealed that highly dispersed Ag+ cations were predominant on 2% Ag/Al2O3, while more metallic Ag clusters with large sizes were present ...
