Abstract
A method for converting soot particles of an exhaust gas includes providing at least nitrogen dioxide or oxygen in the exhaust gas, ionizing soot particles with an electric field, depositing electrically charged soot particles on inner channel walls of at least one surface precipitator, and bringing at least nitrogen dioxide or oxygen into contact with the deposited soot particles on the inner channel walls of the at least one surface precipitator. A device for carrying out the method includes at least one surface precipitator having a plurality of channels through which the exhaust gas can flow and extending between an inlet region and an outlet region, and at least one deposit inhibitor for electrically charged soot particles provided in at least part of the inlet region, especially allowing the soot particles to be evenly deposited and the surface precipitator to be continuously regenerated.
