Title: Denitration process for coke oven exhaust gas
Inventor: KITAGUCHI HISATSUGU
IPC: B01J23/34
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To protect a manganese ore catalyst from sulfur oxide to prevent lowering of the denitration activity when coke oven exhaust gas is denitriated by an ammonia catalytic reduction using a denitration reactor, by providing a granular dust holding material layer in the denitration reactor before the denitration at a manganese ore catalyst packed layer. SOLUTION: Exhaust gas A discharged from a coke oven 1 is introduced into a denitration reactor 2 comprising a dust holding material layer 3 at an inlet and a manganese ore catalyst layer 4 and at first most of dust in the exhaust gas A is captured by the layer 3. Since most of the dust is in the form of soot deposited in the form of solid by the pyrolysis of hydrocarbon in combustion gas and has the capability of adsorbing sulfur oxides, sulfur oxides are adsorbed and removed by a dust layer formed on the surface of the dust holding material. Thereafter, in the layer 4, the exhaust gas A is brought into contact with ammonia B introduced from outside so that nitrogen oxides are reduced and the exhaust gas A, desulfurized and denitrated, is discharged to the atmosphere.
