The invention relates to a device for the catalytic treatment of exhaust gases of motor vehicles which comprises a catalyst substrate designed as a hollow cylinder, an inlet-side and an outlet-side gas baffle and an outer wall, wherein the gas baffles enclose the catalyst substrate and the outlet-side gas baffle and the catalyst substrate form a first cavity into which an exhaust-gas stream can be fed, passing through the catalyst substrate and entering a second cavity which is surrounded by outer wall, gas baffles and catalyst substrate, wherein the outlet-side gas baffle has gas vents, and wherein the recessed part of the outlet-side gas baffle is beaded, with the result that the catalyst substrate is fixed. The invention also relates to a process for the production of the device according to the invention and its use, plus a method for cleaning exhaust gases of motor vehicles.

Catalyst for an exhaust gas aftertreatment system for internal combustion engines

The present invention relates to a catalyst support body () with a longitudinal axis () comprising a honeycomb body () and a housing (), wherein the honeycomb body () consists of at least three metal layers () arranged one above the other, which are wound with their end surfaces in each case starting from a common centre into layers lying one above the other in the form of a spiral and are secured in the sleeve of the housing (), wherein the metal layers consist of metal-foam layers, and wherein a metal-foam layer developed as a corrugated sheath () is arranged between two planar metal-foam layers (), wherein attachment sections () on the outside of the corrugated sheath () connect it to the planar metal-foam layers ().
