摘要: This catalyst system simultaneously removes ammonia and enhances net NOx conversion by placing an NH 3 -SCR formulation downstream of a lean trap. By doing so, the adsorbs from upstream trap generated during rich pulses. The stored then reacts with emitted trap—enhancing rate significantly, while depleting ammonia. combining catalyst, allows for reduction or elimination slip, in spikes thus improved operation.
