Abstract

A multicomposite active absorbent was prepared using the liquid-phase complex of NaClO 2 and NaClO as well as solid-phase slake lime to simultaneous desulfurization and denitrification at a flue gas circulating fluidized bed (CFB). The effects of influencing factors on the removal efficiencies of SO 2 and NO were investigated. Removal efficiencies of 96.5% for SO 2 and 73.5% for NO were obtained, respectively, under the optimal experimental conditions. The characterization of the spent absorbent was carried out by using energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and chemical analysis methods, from which the simultaneous removal mechanism of SO 2 and NO based on this absorbent was proposed.
