Abstract
Abstract The incorporation of a Group IB metal with a Group VIII nonnoble metal or Group VIII1 noble metal (Ru or Os) as a bimetallic catalyst, and possibly an alloy, results in the formation of a catalyst which, when used in a hydrocarbon conversion process, minimizes the hydrogenolysis activity of the Group VIII metal while maintaining or enhancing the catalytic activity of the Group VIII metal for conversion processes such as hydrogenation, dehydrogenation, or aromatization.
