摘要： The invention pertains to the techniques for removing nitrogen oxides (NOx) contained in the exhaust gas discharged from boilers or the like. When the exhaust gas temperature is 100 DEG C or below, preferred is a heat treated activated carbon prepared by heat-treating an activated carbon as the raw material in a nonoxidizing atmosphere at 600 to 1200 DEG C and removing the oxygen-containing functional groups present on the surface thereof to lower the atomic ratio of the surface oxygen to the surface carbon below 0.05. When the exhaust gas temperature exceeds 100 DEG C, preferred is a heat treated activated carbon prepared by heat-treating an activated carbon as the raw material in a nonoxidizing atmosphere at 600 to 1200 DEG C and activating the surface of the activated carbon with sulfuric or nitric acid to give rise to oxidizable oxygen-containing functional groups on the surface.

摘要： A method for denitration of combustion exhaust gas suitable for countermeasure for a low temperature exhaust gas produced at a start-up of a combustion device or for denitration of a low temperature part of the exhaust gas. The denitration method, in which denitration is performed by passing a combustion exhaust gas through an ammonia reduction denitration apparatus, comprises the steps of installing a bypass provided with a low temperature denitration apparatus and disposed on the downstream side of the ammonia reduction denitration apparatus in an exhaust gas flow passage, causing the low temperature denitration apparatus to perform denitration by passing the exhaust gas through the bypass when an exhaust gas temperature is low, causing the ammonia reduction denitration apparatus to perform denitration at a point of time when the ammonia reduction denitration apparatus comes to function fully, and regenerating a catalyst of the low temperature denitration apparatus while the bypass is closed. Further, the denitration method can perform denitration and regeneration of the catalyst by successively switching between low temperature denitration apparatuses of more than one systems which are installed in parallel in an area where a temperature of the exhaust gas in the exhaust gas flow passage ranges from room temperature to 200 DEG C.

摘要： An activated carbon effective in treating flue gas can be produced by heat-treating a starting activated carbon (such as activated carbon fibers made from polyacrylonitrile or pitch) in a non-oxidizing atmosphere. The preferable heat treatment temperature for producing an activated carbon for flue gas desulfurization ranges from 600 to 1200 DEG C, while that for producing one for flue gas denitrification ranges from 600 to 1000 DEG C. The desulfurization using the activated carbon obtained by the heat treatment can lower the concentration of sulfur oxides in flue gas to 5 ppm or below. Further, the concentration of nitrogen oxides in flue gas can be lowered to 1 ppm or below by combining the denitrification using the above activated carbon with the conventional selective catalytic reduction.
