Abstract. A detailed kinetic model of NOx storage and reduction, in the presence of H2O and CO2, with hydrogen as the reducing agent was developed and validated in this study. The mechanism was derived from flow reactor experiments conducted at 200–400 ◦C over a Pt/Ba/Al monolith sample. The detailed kinetic model is divided into four sub-models: (i) NO oxidation over Pt, (ii) NOx stora…
Abstract. The influence of the preparation procedure on the performance of NOx storage and reduction catalysts was investigated by means of flow reactor experiments. Three catalysts were examined; one Pt/Al and two Pt/Ba/Al samples. One of the Pt/Ba/Al samples was prepared with Pt impregnated on Al/Ba and one with Ba impregnated on Al/Pt. The results clearly show that the preparation proced…
