摘要
PROBLEM TO BE SOLVED: To provide a regenerating method for recovering desulfurization capability when the desulfurization capability of active carbon catalyst for the flue gas desulfurization in removing and recovering a sulfurous acid gas as sulfuric acid by contacting with an exhaust gas containing the sulfurous acid gas to adsorb and oxidize the sufurous acid gas is decreased due to the deposition of elemental sulfur, polysulfide or polythionic acid on the catalyst.;SOLUTION: The active carbon catalyst for removing and recovering the sulfurous acid gas as sulfuric acid by contacting the exhaust gas containing the sulfurous gas to adsorb and oxidize the sulfurous acid gas is regenerated by washing the active carbon for the flue gas desulfurization with an aqueous hydrogen peroxide solution. In this case it is preferable that the active carbon catalyst for the flue gas desulfurization is further washed with water or a basic aqueous solution. Preferably, the aqueous hydrogen peroxide solution is a water solution containing 1-15 wt.% of hydrogen peroxide.;COPYRIGHT: (C)2005,JPO&NCIPI
