- •
DeNOx performance of coupled NSR-SCR systems based on Cu/zeolites are compared.
- •
NSR-SCR tests are performed with Cu-SCR granulated and monolith catalysts.
- •
NSR-Cu/CHA achieved higher DeNOx efficiency and much higher hydrothermal resistance.
- •
NSR-Cu/CHA achieves total NOx-to-N2 conversion with no NH3 slip, from 220 to 380 °C.
