摘要：

In this paper we propose an effective global kinetic model that allows prediction of N2O and NH3 formation during the reduction of stored NO (x) in dependence on the composition of the rich mixture (H-2/CO/C3H6), actual operating temperature, and length of regeneration period. A bench flow reactor equipped with a high-speed FTIR was used to measure dynamic evolution of gas components during periodic lean/rich operation of a fully formulated NSRC catalyst (PtPdRh/Ba/Ce-Zr/Mg-Al/Al2O3).
