Expected N2O formation after oxidation of NH3 in SDPF

摘要

A method in anticipation of NO formation after oxidation of NH in SDPF according to an embodiment of the present invention may include measuring an initial NH 3 absorption amount in SDPF, determining a first average NH 3 absorption amount by subtracting a NH 3 slip amount from SDPF from the initial one NH absorption amount in SDPF, determining a second mean NH 3 absorption amount by subtracting an amount of NH to NO and N oxidized from the first mean NH absorption amount, determining the NO generation amount in SDPF, and determining a final NH 3 absorption amount in SDPF by subtracting the NO generation amount from the second average NH absorption amount.
