x 3x 3x x x x x 33 x x x This catalyst system simultaneously removes ammonia and enhances net NOconversion by placing an NH-SCR catalyst formulation downstream of a lean NOtrap. By doing so, the NH-SCR catalyst adsorbs the ammonia from the upstream lean NOtrap generated during the rich pulses. The s...
