| description | PROBLEM TO BE SOLVED: To provide an exhaust emission control system capable of removing a noxious material from exhaust gas without heating the noxious material. SOLUTION: An exhaust gas flow passage 3 is provided with a discharge plasma reaction part 4 and a nitrogen oxide reduction catalyst 8. The discharge plasma reaction part 41 is provided with a filter structural element 7. Meanwhile, a power source 6 for generating discharge plasma is connected to the discharge plasma reaction part 4, and an electrical field is generated at the discharge plasma reaction part 4 and discharge plasma is generated. A particulate material contained in exhaust gas is captured by the particulate material capturing function and the electric dust arresting function, accompanied with formation of an electric field, of the filter structure element 7, and the captured particulate material is combustion-treated by the action of discharge plasma to regenerate the function of the filter. Further, a nitrogen oxide contained in exhaust gas X is oxidized and meanwhile, a given chemical species are produced, the nitrogen oxide contained in exhaust gas is reduced through reduction decomposition reaction of the nitrogen oxide by the produced chemical specifies and a nitrogen oxide reduction catalyst 8.
