Abstract
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.
Claims2
A hydrocarbon reforming catalyst comprising a cylindrical refractory support consisting essentially of alumina in the alpha phase, said support having a surface area of not more than 15 square meters per gram and having two or more gas passages extending axially therethrough from one end to the other and a catalytically active amount of nickel or cobalt oxide deposited there upon in a concentration of from 6 to 30% by weight expressed as the metal, said catalyst having a Relative Activity Coefficient Factor (ACF.sup.R) and a Relative Pressure Factor (PF.sup.R) in excess of that when compared to a standard ring, said (ACF.sup.R) being in excess of 1 and the ratio of said (ACF.sup.R) to said (PF.sup.R) being in excess of 1:1, the height (H) of said support bearing a relationship to the effective internal diameter of each of said gas passages (ID), the ratio of H:ID being less than 4:1.
