Abstract
The catalyst means for the catalytic treatment of exhaust gas have at least one catalyst support with a packet of alternating first and second sheet metal members. Each first sheet metal member has a main section with a number of protuberances, for example waves. The second sheet metal members have a main section resting against the wave summits of at least one adjacent, first sheet metal member. Coatings comprising an alumina layer and catalytically active material are applied to the main sections which together bound passages for the exhaust gas. Each sheet metal member is connected in at least one retaining section rigidly to a member of retaining means and/or is held by said member a distance away from a retaining section of another sheet metal member. This makes it possible to connect the sheet metal members to one another in a stable and permanent manner without them being damaged by excessive compressive forces and/or movements.
