An apparatus for removing SO2 and/or NO x from an exhaust gas formed by the combustion of oil is provided herein. The apparatus includes a conduit for discharging the exhaust gas to the open air, and a screen portion fitted to the conduit across the conduit. The screen portion accommodates an activated carbon which comprises both carbon microcrystals which are irregularly arranged and difficultly- graphitizable carbon which includes crosslinking lattices in the gaps among carbon microcrystals. The activated carbon has a pencil hardness of from B to 6B, a pore size of 100-400 .ANG., a specific surface area of 150-500 m2/g, and a pore volume of 1.3-5.0 ml/g. A first end of the screen portion is open to the outside, and has a means for feeding new activated carbon thereinto. A second end of the screen portion is also open to the outside, and includes a means for discharging used activated carbon therefrom near the second end opening. Means are provided for controlling the feeding of the new activated carbon and the discharging of the used activated carbon by detecting the amount of the discharged used activated carbon.
