Catalytic reactor having radial leaves
First Claim
1. A reactor comprising a plurality of metal leaves, each leaf extending from an interior region to an exterior region of the reactor, at least some of the leaves being at least partly coated with a catalyst, the interior region being bounded by a generally cylindrical pipe, the exterior region being bounded by a generally cylindrical tube, each leaf extending toward but not penetrating through the pipe, each leaf comprising (a) a flat central portion disposed in a central region between the pipe and the tube and (b) a first flat edge portion located between the central portion and the pipe and angled relative to the central portion, each first flat edge portion extending outwardly from the pipe and being interleaved between a pair of adjacent first flat edge portions.

Abstract
A reactor includes a plurality of metal leaves which extend from an interior of the reactor to its exterior. The leaves occupy a space between an internal mandrel and an external tube. In one embodiment, the leaves are generally flat pieces of foil, stacked together so that they do not touch except at spacers formed in the pieces. In another embodiment, the leaves are formed of a pleated and crimped foil, each leaf being defined by a piece of foil that has been folded over upon itself. In both embodiments, the leaves extend from the internal mandrel, radially outward to an inner surface of the tube. The reactor facilitates the transfer of heat between the outside of the reactor and its inside region.
