    摘要： This invention relates to a technique for removing nitrogen oxides (NOx) present in exhaust gases discharged from boilers and the like. When the temperature of the exhaust gas is 100° C. or below, a heat-treated active carbon produced by heat-treating a raw active carbon at 600 to 1,200° C. in a non-oxidizing atmosphere so as to remove oxygen-containing functional groups present at the surfaces thereof and thereby reduce the atomic surface oxygen/surface carbon ratio to 0.05 or less is preferably used. When the temperature of the exhaust gas exceeds 100° C., a heat-treated active carbon produced by heat-treating a raw active carbon at 600. to 1,200° C. in a non-oxidizing atmosphere and activating the surfaces thereof with sulfuric acid or nitric acid to impart oxidizing oxygen-containing functional groups thereto is preferably used.

    摘要： CaS oxidation has CaS particles oxidized into CaSO4 completely as far as to the interior of the particle. The interior of an oxidation apparatus 1 is partially partitioned by a partition 22 to thereby form a first fluidized bed 20 on the inner side, a second fluidized bed 21 on the outer side and a space portion 23 thereabove. A heat exchanger 27 having a baffle plate is disposed on the inner side of the partition 22 and an in-bed heat exchanger 33 is disposed on the outer side of same. A desulfurizing product-containing fine powder 204 and coarse powder 205 and a mixture gas 206 of nitrogen, oxygen and steam are supplied into the second fluidized bed 21. Also, coal 200 and coal char 201 are supplied into the first fluidized bed 20 from below. Of the particles 304 oxidized in the second fluidized bed 21 and supplied into the first fluidized bed 20 from below with the flow of a mixture gas 208, the fine powder entrains into the space portion 23 as entrained particles 300 and a major part thereof falls down into the second fluidized bed 21 as particles 207. The completely oxidized particles are discharged as discharged ash 303 and entrained ash 302.
