Abstract
Effects of CaO, MgO, Fe2O3 and sintering ores on NO reduction by CO was investigated with or without oxygen present. The NO reduction reaction was carried out in a fixed bed quartz reactor with CaO, MgO, Fe2O3 and sintering ore as bed materials under the temperature range from 600°C to 1000°C. The results showed that the order of the catalytic effect on NO reduction by CO was, CaO > sintered ores > Fe2O3 > MgO. Under the action of the sintered ores, the NO conversion was over 90% with 1.2% CO. The presence of oxygen didnt favor the NO reduction by CO.
