Abstract

Catalityc removal of nitrogen oxide from combustion gases Nitrogen oxide conversion to nitrogen over Pt/Al2 O3, Pd/Al2O3, Rh/Al2O3 catalysts was investigated. The results of the catalytic activity investigations, with the iso-x method, showed that NO reduction by methane occurs at a reasonable rate at the temperature range 200-500°C. Alumina-supported Pd, Pt and Rh catalysts have been compared for the selective reduction of NO to N2. All the catalysts showed good activity in NO reduction by methane, giving around 80 - 90% N2 production. At moderate temperatures Pt is the most active catalyst for the removal of NO.
