ABSTRACT:
An electrically heatable honeycomb body, in particular for cleaning exhaust gas originating in an internal combustion engine. The honeycomb body has at least two zones arranged in series in the flow direction with different coatings. The honeycomb body preferably has a first zone and a second zone which is arranged downstream, the first zone having an adsorbing coating, and the second zone having a catalytically active coating. The electrically heatable honeycomb body serves in particular as a trap for pollutants, preferably hydrocarbons or nitrogen oxides, which are contained in the exhaust gas. The configuration of the adsorbing first zone is matched to the light-off performance of the electrically heatable honeycomb body.
