Popis:	Reburning is effective to control NO emission. The paper presents a short review on recent research on catalysis reduction of NO and HCN/NH3by some metal and their oxides during reburning. The major difficulties that limit NO reduction efficiency by reburning involve the re-oxidation of the intermediate products during reburning, HCN/NH3and char nitrogen to NO. So far, results showed that Fe2O3could reduce the formation of HCN/NH3after reburning and metallic iron could directly reduce NO to N2. Temperature and co-existing gases influenced the catalysis performance of Fe and its oxides. Detailed mechanism and kinetics of the reactions should be further investigated.
