Abstract

A fuel processor with a floating catalyst has a reactant gas passage and a product gas passage separated by a separating wall which is fixed at one end and free at the other end, to permit differential thermal expansion. The catalyst is received inside the separating wall proximate to the free end. An outer wall at least partially surrounds the separating wall and the fixed end of the separating wall may be joined to the outer wall. The fuel processor may comprise a plurality of concentric tubes, and may include a third tube located inside the separator wall. The gas passages are provided with gas permeable support structures such as turbulizers or fins which support the separating wall relative to the outer wall, but the support structures are bonded to only one tube in order to permit differential thermal expansion of the walls.

First claim

What is claimed is:

1. A fuel processor, comprising:
(a) a reactant gas passage;
(b) a product gas passage;
(c) a separating wall which separates the reactant gas passage from the product gas passage, the separating wall having a fixed end and a free end, wherein the fixed end is proximate to a reactant gas port and a product gas port;
(d) a catalyst received inside the separating wall proximate to the free end thereof, wherein the reactant gas passage extends from the react…
