Abstract: A hydrocarbon conversion process and catalyst, the latter comprising a transition metal, or other hydrogenationdehydrogenation component of said metal, composited with a nonstoichiometric titanium carbide support, particularly a support wherein the titanium carbide is an interstitial solid solution that possesses a stable phase over the stoichiometric range TiC0.52 to TiC0.99, and preferably within a range of TiC0.70 to TiC0.95. Such catalysts are useful for such hydrocarbon conversion processes as hydrogenationdehydrogenation, hydrofining, hydrodesulfurization and reforming. By varying the stoichiometry of the titanium carbide support within the limits described, an interaction is created between the hydrogenation-dehydrogenation component and the support, and the activity and selectivity of the reactions can be controlled and optimized.
