High performances of Pt-K/Al2O3 versus Pt-Ba/Al2O3 LNT catalysts in the simultaneous removal of NOx and soot
TL;DR: In this paper, the potentiality of a Pt-K/Al2O3 catalyst in the simultaneous removal of particulate matter (soot) and NO -consuming NO-consuming vehicles was investigated by means of Temperature Programmed Oxidation (TPO) experiments and Transient Response Method (TRM), and compared with Pt-Ba/Al 2O3.
Journal ArticleDOI
How to control the selectivity in the reduction of NOx with H2 over Pt-Ba/Al2O3 Lean NOx Trap catalysts
TL;DR: In this article, the reduction process of NOx species stored over Pt-Ba/Al2O3 Lean NOx Trap systems is analyzed when H2 is used as a reductant.
Journal ArticleDOI
Experimental investigation of the reduction of NOx species by CO and H2 over Pt–Ba/Al2O3 lean NOx trap systems
TL;DR: In this paper, the reactivity of NOx stored at 350°C onto Pt-Ba/Al2O3 LNT catalyst in the reduction by H2, CO and CO/H2O mixture is investigated by means of transient experiments and complementary FT-IR analyses.
Journal ArticleDOI
Pathways for N2 and N2O Formation during the Reduction of NOx over Pt–Ba/Al2O3 LNT Catalysts Investigated by Labeling Isotopic Experiments
TL;DR: In this paper, the formation of N2 and N2O during the reduction of gas-phase NO and of NOx stored over a model PtBa/Al2O3 NSR catalyst was investigated using unlabeled ammonia and labeled NO.
Journal ArticleDOI
Effect of soot on the storage-reduction performances of PtBa/Al2O3 LNT catalyst
TL;DR: In this paper, the effect of soot on the storage-reduction performances of a PtBa/Al 2 O 3 catalyst is investigated, and it is found that the presence of soots reduces the NO x storage capacity of the catalyst, evaluated in presence of water and CO 2 in the feed stream in the range 200-350 Â c and with different values of the NO inlet concentration.
