METHOD FOR ACTIVATING INPLANT OF CARBON BASED ADSORBING MATERIAL AND METHOD FOR TREATING EXHAUST GAS

PROBLEM TO BE SOLVED: To provide a method for activating inplant maintaining internal strength of a carbon based adsorbing material and inhibiting a pulverization using a device for treating an exhaust gas in which an exhaust gas of 130°C or lower containing sulfur oxide is introduced into a moving layer type reaction tower filled with the carbon based adsorbing material to carry out a treatment of the exhaust gas and, after the adsorbing material discharged from the reaction tower is introduced to a regeneration tower to heat and regenerate it, it is again fed to the reaction tower; and to provide an exhaust gas treating method for treating an exhaust gas of 130°C or lower while replenishing the carbon based adsorbing material worn accompanying with the exhaust gas treatment and activating the inactivated carbon based adsorbing material. SOLUTION: In the method for activating the inplant of the carbon based adsorbing material, a molar ratio of ammonia contained in the activating carbon based adsorbing material fed to the regeneration tower to sulfur oxide is adjusted to a range of 0.1 to 1.0. In the method for treating the exhaust gas, a molar ratio of ammonia added into the exhaust gas to sulfur oxide is made to 1.0 or lower and a molar ratio of ammonia contained in the carbon adsorbing material fed to the regeneration tower to sulfur oxide is adjusted to a range of 0.1 to 1.0.
