An improved catalyst is described which comprises a normally cylindrical refractory support having gas passages communicating from end to end and oriented parallel to its axis and having gas passages in the shape of segments of circles (pie-shaped), square, hexagonal, circular, oval or sinusoidal. The exterior and interior surfaces are coated with catalytic compositions. The length of the refractory support is significantly less than the diameter. Further, there is a definite ratio of height to effective internal diameter (H:ID) of each of the gas passages. These catalysts are especially effective for endothermal reactions because both the internal and external surfaces of the support are coated with catalysts and are more efficiently heated. This is especially true for the internal surfaces of the support (i. e. , the walls of the axially oriented gas passages) which heretofore have been shielded from the infra-red rays radiating from the tubes of the catalytic reactor.

An improved catalyst and an improved process for use of the catalyst in the steam-hydrocarbon reforming reaction is disclosed. The catalyst comprises a group VIII metal on a cylindrical ceramic support consisting essentially of alpha alumina and having a plurality of gas passages extending axially therethrough. These supported catalysts display a higher geometric surface area and a lower pressure drop than do standard rings.
