A dual-bed catalytic system has been developed for the complex after treatment of diesel engine exhaust gases comprising nitrogen oxides, CO, hydrocarbons, and residual NH3 (NH3-slip) within wide temperature range. The system demonstrates effective NOx abatement at 200–500 °C. The upstream bed (FeBeta) is responsible for the selective catalytic reduction of NOx by ammonia (NH3-SCR) above ~ 300 °C, while the downstream bed ([Mn–Ce/CeO2–ZrO2 + FeBeta] combined catalyst) provides effective NOx abatement below 300 °C and total oxidation of CO, hydrocarbons, and NH3-slip.
