A catalyst support is formed of a monolith having corrugated metal leaves. The corrugations of each leaf are oblique relative to the edges of the leaf. Each leaf extends from an interior region to an exterior region, and has corrugations that are non-parallel to the corrugations in an adjacent leaf. Each leaf also includes slits, and is coated with a suitable catalyst. A set of monoliths, made as described above, are stacked within a cylindrical pipe. The corrugations define gas flow channels, which enable heat applied to the exterior of the pipe to travel to the center of the monolith, and back to the outside. The support of the present invention thus facilitates heat transfer to essentially all regions of the monolith. The invention also inherently overcomes the problem associated with thermal mismatch between the metal pipe and a ceramic catalyst material.
A catalyst support comprising a plurality of monoliths arranged within a generally cylindrical pipe, each of said monoliths having an exterior region, in a vicinity of said pipe, and an interior region, each of said monoliths comprising a plurality of corrugated metal leaves, each leaf being coated with a catalyst effective to catalyze a catalytic reaction, said corrugated leaves defining a plurality of gas flow channels, some channels adapted to lead gas from the exterior region to the interior region and other channels adapted to lead gas from the interior region to the exterior region.
