Carrier body for exhaust-gas aftertreatment with dispersed catalyst configuration, process for producing a carrier body and exhaust gas treatment unit and vehicle having a carrier body |
摘要 |
A carrier body includes an overall surface having at least one coating portion with a catalytically active coating including at least one type of catalyst elements disposed in dispersed form at a surface of the carrier body. The catalyst elements have a mean spacing along the surface of at least 3 micrometers. The surface has a mean roughness depth Rz of 2 to 10 micrometers. The carrier body has a maximum increase in pressure loss compared to a carrier body with a smooth and uncoated surface of 25%. A process for producing a carrier body and an exhaust gas treatment unit and a vehicle having a carrier body, are also provided.
