Activity and characteristics of "Oxygen-enriched" highly ...

Abstract. An "Oxygen-enriched" highly reactive absorbent was prepared by mixing fly ash, lime and a small quantity of KMnO 4 for simultaneous desulfurization and denitrification. Removal of SO 2 and NO simultaneously was carried out using this absorbent in a flue gas circulating fluidized bed (CFB). The highest simultaneous removal efficiency, 94.5% of SO 2 and 64.2% of NO, was achieved ...
