Abstract
A novel sorbent, potassium carbonate impregnated on porous fine alumina, wa s produced, and its reactive and regenerative properties were evaluated for dry-type simultaneous removal of SO2 and NO from flue gas under stack temp eratures, by using a powder-particle fluidized bed (PPFB) with I.D. of 53 m m as the reactor. High removal efficiencies for SO2 and NO were achieved si multaneously An apparent beneficial effect of SO2 on the enhancement of NO removal was found based on a large amount of data. The alumina carrier was successfully regenerated and used repeatedly for the production of fresh so rbent particles. With no ammonia,low temperature, high removal efficiency a nd no second waste emission as main characteristics, this dry process can b e a competitive technology for pollution control of flue gas from power pla nts in the future.
