Abstract
Abstract A catalyst carrier body and a method for producing the same, includes layers of textured curved metal sheets through which a fluid can flow, a jacket in which the curved metal sheets are disposed, and at least one supporting wall disposed in and firmly joined to the jacket forming a supporting structure for the body, the curved metal sheets being individually secured to the supporting walls for absorbing radial expansions of the supporting structure through changes in the curvature of the sheets.

Claim 9
Dependent Claim
16 words
Catalyst carrier body according to claim 1, wherein said curved sheets have legs with different lengths.
Claim 10
Dependent Claim
45 words
Catalyst carrier body according to claim 1, wherein said jacket is divided into sections, and said layers of said curved sheets are bent in a substantially U or V-shape defining two ends each being secured on the same side of one of said jacket sections.
Claim 11
Dependent Claim
29 words
Catalyst carrier body according to claim 1, wherein said curved sheets of said layers are secured to said at least one supporting wall by a brazed or welded connection.
Claim 12
Dependent Claim
35 words

Claim 13
Dependent Claim
49 words
Catalyst carrier body according to claim 1, wherein said at least one supporting wall has at least one welded seam including said sheets of said layers in contact with said at least one supporting wall, said welded seam having a sag at the root thereof forming a form-locking connection.
Claim 14
Dependent Claim
36 words
Catalyst carrier body according to claim 1, wherein said sheets of said layers have end surfaces with points of contact, and said sheets are at least partially brazed to one another at said points of contact.
Claim 15
Dependent Claim
43 words
Catalyst carrier body according to claim 1, wherein said jacket and said layers of curved sheets are formed of at least two segments, said segments each being in the form of at least one different spirally-wound cut-apart blank combined in a different manner.
Claim 16
Dependent Claim
