摘要： A method for treating an exhaust gas containing nitrogen oxides, oxygen and soot, in which the nitrogen oxides are selectively reduced into nitrogen by adding ammonia to the exhaust gas as a reducing agent under existence of a catalyzer, is improved in that the nitrogen oxide is removed by introducing the exhaust gas into a denitration reactor in which a plurality of planar catalyzer packs or catalyzer packs having gas passage holes are arrayed in parallel to a gas flow and a linear velocity of the gas through the reactor is selected at 4-15 m/s. In one preferred mode of the method, soot having a relatively large particle diameter is preliminarily removed by a dust remover disposed upstream of the reactor, while most of the remaining soot is removed by a high performance dust collector disposed downstream of the reactor. Denitration reactor structures suitable for the improved method for treatment are also disclosed herein.
