Effective Model for Prediction of N2O and NH3 Formation During the Regeneration of NOx Storage Catalyst
In this paper we propose an effective global kinetic model that allows prediction of N 2 O and NH 3 formation during the reduction of stored NO x in dependence on the composition of the rich mixture (H 2 /CO/C 3 H 6 ), actual operating temperature, and length of regeneration period. A bench flow rea...
