  • METHOD OF TREATING EXHAUST GAS AND SYSTEM FOR SAME
    Publication number: 20230347326
    Abstract: A method of treating exhaust gas from a lean burn internal combustion engine is disclosed. The method comprises: introducing ammonia or an ammonia precursor into the exhaust gas upstream of an Fe-SCR catalyst, the Fe-SCR catalyst comprising iron and a zeolite; and contacting the exhaust gas with the Fe-SCR catalyst; wherein the amount of ammonia or ammonia precursor introduced into the exhaust gas upstream of the Fe-SCR catalyst is controlled to provide an ammonia-to-NOx molar ratio (ANR) in the exhaust gas contacting the Fe-SCR catalyst of from greater than 2 to 6.
