The introduction of a Pt-Re bimetallic reforming catalyst in the late 1960's had an immediate impact and revolutionized the reforming technology, much as the introduction of the Pt-Al{sub 2}O{sub 3} catalyst had done about twenty-five years earlier. Following the initial introduction of the catalyst, probably the most popular view to explain its greater stability was that of alloy formation. More detailed studies of this bimetallic catalyst system led to data that was viewed, on the one hand, to support alloy formation and, on the other hand, to support metallic Pt and ionic Re as well as to indicate that catalyst preparation and pretreatment may play an important role in determining the chemical state of the metals. While not nearly as widely utilized at Pt-Re in commercial operation, Pt-Sn supported bimetallic catalysts have also received widespread attention. This note describes some conflicting catalyst characterization data for Pt-Sn supported catalysts and the presentation will relate the characterization data and the alkane dehydrocyclization/alkyl cyclopentane hydrogenolysis selectivity of Pt-alumina and Pt-Sn-alumina catalysts.
