Experiment Study On New Highly Active Absorbent For Flue Gas Desulfurization And Denitrification

Fly ash,Ca(OH)2 were used as the basal materials which exploit the highly active absorbents, more research was carried on to manufacture the highly activeabsorbents which can simultaneous remove the SO2 and NOX from flue gas. Experiments on simultaneous desulfurization and denitrification were carried out at the fixture bed and duct injection, the best experimental terms on preparing the highly active absorbents, the influencing factors for the efficiencies of desulfurization and denitrification were investigated. The best reaction conditions of CFB were found and at best reaction conditions, 94.5% desulfurization ,64.2% denitrification efficiency using the highly active absorbents by wet process and 62.8% desulfurization ,38.8% denitrification efficiency using the highly active absorbents by dry process can be achieved. Characteristic analysis of the highly active absorbents was studied, furthermore the mechanism of preparation and removal SO2, NOX was investigated. Study works of the dissertation provide valuable references for pollution control of flue gas.
