<P>PROBLEM TO BE SOLVED: To provide a reforming device for generating a reducing agent capable of selectively reducing NOx, and to obtain a reducing agent from fuel of an internal combustion device in an exhaust emission control device for purifying exhaust gas of the internal combustion engine by selective reduction reaction. <P>SOLUTION: In the reforming device including a reforming part 150 that subjects a hydrocarbon-based raw material to be reformed to a reforming reaction to form a reducing agent to be supplied to a reducing catalyst 14 for reducing nitrogen oxide selectively, and a hydrogen atom supply means 151 supplying hydrogen atoms to the reforming part 150, the raw material to be reformed is reformed to the reducing agent by reacting, when the raw material passes through a reforming reaction area in the reforming part 150, with hydrogen atoms supplied by the hydrogen atom supply means 151. In the exhaust emission control device provided with this reforming device, the reducing catalyst 14 is provided within an exhaust gas passage 12 through which exhaust gas of the internal combustion engine 10 is passed so as to selectively reduce nitrogen oxides in the exhaust gas. The raw material to be reformed is the fuel used for the internal combustion engine 10. <P>COPYRIGHT: (C)2007,JPO&INPIT |
