摘要： An air pollution control apparatus includes at least one denitration catalyst layer for reducing the amounts of nitrogen oxides in flue gas from a boiler and oxidizing mercury with hydrogen chloride sprayed into the flue gas. Spraying pipe headers 51 are disposed in a flue gas duct 19. The spraying pipe headers 51 are inserted into the flue gas duct 19 and arranged in a direction orthogonal to the direction of a gas flow in the flue gas duct 19. At least four spray nozzles 52-1 to 52-4 are disposed at intervals on the spraying pipe header 51 to form a vertical vortex flow 53 in the gas flow direction. A swirling diffuser plate is disposed on an opening side of the spray nozzles to form the vertical vortex flow in the gas flow direction, wherein the swirling diffuser plate has a flat shape at one side parallel to the spraying pipe header and a wavy shape corresponding to the nozzle intervals on the header at the other side. The diffusion of hydrogen chloride is thereby facilitated in a rapid manner. Therefore, the number of the nozzles can be reduced, and the uniformity of the concentration of hydrogen chloride at the location of the catalyst can be ensured even when the spacing between the nozzles is increased.

摘要： In an exhaust gas treatment, the amount of a highly corrosive mercury-halogenating agent to be added is reduced with the mercury-removing efficiency maintained high.A mercury-halogenating agent (40) and ammonia (30) are added to combustion exhaust gas from a boiler, the exhaust gas containing NOx, SOx and mercury. The exhaust gas is brought into contact with a CO/HC oxidation catalyst (50) and is then subjected to reduction denitration (60) in the presence of a solid catalyst. Thereafter, metallic mercury is oxidized to halogenated mercury. Then, the exhaust gas is wet-desulfurized (100) with the alkaline absorbing solution, and the halogenated mercury is removed.

摘要： Provided are a flue gas denitration catalyst having high denitration activity and capable of suppressing a side reaction, that is, oxidation of SO2; and a preparation process of the catalyst. The flue gas denitration catalyst comprises TiO2, WO3 and V2O5. In the surface layer of the catalyst within 200 μm from the surface thereof, V2O5 is supported on a carrier containing TiO2 and WO3. The supported amounts of V2O5 range from 0.4 to 5 wt. % based on the weight of the surface layer and range from 0.1 to 0.9 wt. % based on the total weight of the catalyst. The V2O5 thus supported has a crystallite size of less than 10 nm as measured by X-ray diffraction. The catalyst can be available by preparing a mixture containing TiO2 and WO3 and having V2O5 supported on the surface of an extruded product of the prepared mixture by a vapor phase method. The catalyst can be also available by having V2O5 supported on a powder of the prepared mixture by a vapor phase method and having the resulting powder supported on the surface of a formed product.

摘要： In a NOx removal catalyst used for removing nitrogen oxides in flue gas, when a silica (Si) component as an inhibitor that causes an increase in a SO2 oxidation rate accumulates on a surface of the catalyst, the silica component accumulating on the surface of the catalyst is dissolved, thereby regenerating the catalyst. Accordingly, the inhibitor such as the silica component covering the surface of the NOx removal catalyst can be removed, thereby enabling to provide a catalyst without having an increase in the SO2 oxidation rate of the regenerated NOx removal catalyst.
