ABSTRACT:
A catalyst constituted of a composite which includes hydrogenation-dehydrogenation components comprised of palladium and platinum in total concentration ranging from about 0.2 to about 0.6 percent, in molar concentration of palladium:platinum ranging from about 1:1 to about 10:1 composited with an inorganic oxide support. In its preferred aspects the catalyst composite also contains rhenium, and more preferably a small amount of copper is added to suppress hydrogenolysis, which is particularly acute in reforming during the early period of operation when the catalyst is placed on stream, i.e., at the startup of a reactor; and process of employing such catalysts in reforming.
