Sinfelt, J H

A naphtha reforming catalyst is claimed consisting essentially of a refractory support in association with greater than 0.1 wt. percent based on total catalyst, of a single catalyst metal selected from the group consisting of iridium, ruthenium and osmium, the surface area of said catalyst metal on said support being at least 150 square meters per gram of catalyst metal as determined by carbon monoxide chemisorption techniques, said catalyst being prepared by a procedure comprising: (a) contacting said support with a solution of a decomposable compound of said catalyst metal, (b) drying said metal-containing support, (c) calcining said metal-containing support at conditions that inhibit the formation of crystalline metal oxides, and (d) reducing said catalyst metal compound to the catalyst metal, said catalyst metal not being present on said support in a crystalline oxide form immediately prior to said reduction.
