Abstract (en)
[origin: WO2006108566A1] The invention relates to a device for use in the treatment of exhaust gases which comprises at least one exhaust gas line (1), through which an exhaust gas flows in a direction of flow (2), a supply (3) for a reducing agent (4) to the exhaust gas line (1), a control unit (5) for dosing the reducing agent (4) to be supplied, a support (6) that is positioned downstream of the supply (4), when seen in the direction of flow (2), and that comprises means for bringing about a chemical reaction of the reducing agent (4) with at least one component of the exhaust gas. The inventive device is characterized in that the support (6) includes at least one metallic base (7) which is at least partially coated with a coating (8) capable of accumulating the reducing agent (4). The invention also relates to two methods for the dosed provision of a reducing agent (4), especially a solid reducing agent. The inventive method and the device for carrying out the inventive method allow to economically use the reducing agent while guaranteeing an approximately 100 % reaction of the nitrogen oxides contained in the exhaust gas.
