ABSTRACT:
A process for producing a catalyst by providing a monolith with a polygonal cross section, tightly enclosing the monolith with a single part jacket made of metal sheet or plate, placing a layer of expanded matting between the jacket and the monolith, bending the jacket with at least one of a bending and a clamping device into a proper final shape so that edges of the jacket which extend at least essentially in a longitudinal direction of the monolith at least contact each other, and undetachably joining the edges to each other.
