摘要： To prevent large quantities of ammonia gas from mixing into a collected sulfur oxide, an exhaust gas processing is carried out by dividing an exhaust gas flow into a plurality of branches, charging an ammonia gas into predetermined ones of these branched exhaust gas flows and supplying the exhaust gas into which the ammonia gas is charged to a predetermined portion of a transverse moving layer (52) in which a carbonaceous catalyst is accommodated. The charging quantity of the ammonia gas is adjusted so that the molar ratio of NH4 /S4O absorbed to the carbonaceous catalyst discharged from the bottom of the moving layer (52) and supplied to a regenerator (18) becomes not greater than 1. Since the carbonaceous catalyst absorbs SO4 as the moving layer (52) moves down, the molar ratio of NH4 /SO4 in the carbonaceous catalyst discharged from a moving layer reactor (11) becomes sufficiently small.

摘要： An exhaust gas treatment process capable of preventing mixture of a large amount of ammonia gas into collected sulfur oxides. An exhaust gas flow is divided into a plurality of exhaust gas flows. Ammonia gas is introduced into exhaust gas of a predetermined exhaust gas flow among the exhaust gas flows. The exhaust gas into which ammonia gas has been introduced is charged for treatment into a predetermined portion of the crossflow type moving layer 52 which accommodates the carbonaceous catalyst. The amount of the ammonia gas that is introduced into exhaust gas is adjusted such that the mole ratio between NH 4 + and SO 4 2- (NH 4 + / SO 4 2- ) adsorbed on the carbonaceous catalyst which is discharged from the bottom portion of the moving layer 52 and charged into a regenerator 18 becomes 1 or less. As the carbonaceous catalyst moves downward in the moving layer 52, the carbonaceous catalyst adsorbs SO 4 2- . Accordingly, the NH 4 + / SO 4 2- mole ratio becomes sufficiently low on the carbonaceous catalyst discharged from a moving-layer reactor 11.
