Zusammenfassung:	PURPOSE:To provide a simple and clear method for treating efficiently an SOx and NOx-contg. gas by using a moving bed reactor. CONSTITUTION:A method for treating an exhaust gas wherein an SOx and SOx-contg. gas is brought into contact with a carbon material in a desulfurization and denitrification tower consisting of a carbon material moving bed and the carbon material with lowered activity is regenerated by heating in a regeneration reactor and is treated with ammonia in the temp. range of 400-600 deg.C and this ammonia-treated carbon material is fed into the desulfurization and denitrification tower, is provided. Therefore, there is no possibility that ammonia trouble caused by deposition of an ammonium salt occurs and an efficient desulfurization and denitrification can be performed.
