Abstract
A catalytic reactor or heat exchanger includes a monolith defining a plurality of leaves, the monolith having a generally annular cross-section. The monolith is disposed within a generally cylindrical outer tube, and around a corrugated inner tube. The reactor includes a device for urging the monolith radially outward, so as to maintain contact between the monolith and the outer tube. Such device may include a coned washer, or it may be defined by a folded flap that is integral with the inner tube. In either case, the reactor compensates for metal creep, and virtually insures continued contact between the monolith and the outer tube.
Claims17
A reactor comprising a plurality of metallic leaves, the leaves having surfaces, the reactor defining a plurality of paths for gas flow, the paths being generally parallel to the surfaces of the leaves, the leaves defining a generally annular cross-section as viewed in a direction of said paths for gas flow, wherein the leaves are inserted between an outer metallic tube and an inner tube, and wherein the leaves occupy an annular space between the outer tube and the inner tube, the reactor further comprising means for urging the leaves radially outward so that some of the leaves are in contact with the outer tube.
A reactor comprising:
- a) a generally cylindrical outer tube, and a generally cylindrical inner tube, b) a monolith including a plurality of leaves, the monolith having an annular cross-section and being disposed between the outer tube and the inner tube, and c) means for urging the leaves radially outward, so as to maintain contact between the leaves and the outer tube.
A reactor comprising:
- a) a generally cylindrical outer tube, and b) a monolith including a plurality of leaves, the monolith having an annular cross-section and being disposed within the outer tube and in a vicinity of an inner surface of the outer tube, the reactor further comprising a corrugated inner tube, the monolith being located between the inner tube and the outer tube.
A reactor comprising:
- a) a generally cylindrical outer tube, and b) a monolith including a plurality of leaves, the monolith having an annular cross-section and being disposed within the outer tube and in a vicinity of an inner surface of the outer tube, the reactor further comprising a post disposed along a longitudinal axis of the outer tube.
A reactor comprising:
- a) a generally cylindrical outer tube, and b) a monolith including a plurality of leaves, the monolith having an annular cross-section and being disposed within the outer tube and in a vicinity of an inner surface of the outer tube, the reactor further comprising means for urging the leaves radially outward, so as to maintain contact between the leaves and the outer tube.
