Ruthenium Based Catalysts for NOx Reduction

Abstract: 

The present disclosure is directed at a ruthenium based catalyst for NOx reduction. More specifically, ruthenium based catalysts are used for NOx reduction in an internal combustion engine to reduce NO.sub.X to nitrogen, at relatively high conversion and selectivity, using carbon monoxide and hydrogen as reductants. The ruthenium based catalyst has particular utility in exhaust gas recirculation such as in dedicated exhaust gas recirculation (D-EGR) systems.
