Modelling of NOx storage + SCR exhaust gas aftertreatment system with internal generation of ammonia
Original language description
Combination of an NOx storage and reduction catalyst (NSRC, called also lean NOx trap, LNT) and a catalyst for the selective catalytic reduction of NOx by NH3 (NH3-SCR) offers a potential to significantly increase the efficiency of NSRC-based exhaust gasaftertreatment systems. Under most situations the SCR catalyst is able to adsorb the NH3 peaks generated in the NSRC during the regeneration and utilise it for additional NOx reduction in the course of the consequent lean phase. This synergy becomes more important with the aged NSRC, where generally lower NOx conversions and higher NH3 yields in wider range of operating temperatures are observed (in comparison with the fresh or de-greened NSRC). In this paper we present global kinetic models for the NSRC (Pt/Ba/Ce/?-Al2O3 catalyst type) and NH3-SCR (Fe-ZSM5 catalyst type). The NSRC regeneration by a mixture of CO, H2 and HC is considered with a differentiated activity and selectivity of individual reducing agents in the NOx reduction.
