Experimental and modeling study of a dual-layer (SCRÂ +Â PGM) NH3 slip monolith catalyst (ASC) for automotive SCR after treatment systems. Part 2. Validation of PGM kinetics and modeling of the dual-layer ASC monolith

- Validation of a global kinetic model for the PGM component of the dual-layer ASC.
- Validation of a mathematical model for dual-layer (SCR + PGM) NH3 slip converters.
- Analysis of beneficial features of a dual-layer (SCR on top) ASC configuration.
- Enhanced N2 selectivity for dual-layer compared to single-layer PGM-only washcoat.
- Synergic combination of PGM layer oxidation activity and SCR layer N2 selectivity.
