ABSTRACT:
A spiral-wound metal catalyst support is disclosed, wherein the layers of the spiral cannot telescope outwardly in either direction. The support is formed by first winding together a flat strip and a corrugated strip, the strips being wound on a mandrel. The mandrel is removed to leave an axial hole. The catalyst support is then flattened at each end, so as to close the axial hole at each end. The flattening is done in mutually perpendicular directions, so that the catalyst support has tapers in both of two directions. The tapers prevent telescoping of the layers of the support. The catalyst support can be placed in a tube before it is flattened, and then the tube and the support can be flattened together, so that the support becomes firmly anchored in the tube. In an alternative embodiment, a second, tapered mandrel is inserted into the support before flattening, the tapered mandrel having a shape conforming to the inner cavity defined by the flattened support. The support is thereby anchored on the tapered mandrel, further preventing the layers of the support from telescoping. The invention also includes a method of making the catalyst support.
