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.

Abstract: An improved vanadium-phosphorus mixed oxide is prepared by a unique method employing an organic medium. The substantial intrinsic surface area and the microcrystalline structure of the new oxide result in advantageous activity and selectivity effects in the catalyzed vapor phase oxidation of n-butane to maleic anhydride. These oxides are also useful for the production of acid anhydrides from suitable hydrocarbon feeds.

Abstract: HYDROCARBON CONVERSION CATALYSTS OF IMPROVED ACTIVITY ARE OBTAINED BY ACTIVATING FORMAMINOUS REFRACTORY OXIDES COMBINED WITH AT LEAST ONE THERMALLY DECOMPOSABLE AND/ OR OXIDIZABLE COMPOUND OF A CATALYTICALLY ACTIVE METAL UPON CALCINATION WHILE CONTACTING THE COMPOSITE WITH AN ACCELERATED FLOW OF AN OXIDIZING GAS AT A RATE OF AT LEAST ABOUT 2 S.C.F.M. PER POUND OF SAID COMPOSITE. FURTHER ADVANTAGE IS REALIZED BY HEATING THE COMPOSITE TO THE PRESCRIBED CALCINATION TEMPERATURE AT A CONTROLLED GRADUAL RATE. IT IS ALSO GENERALLY DESIRABLE TO ASSURE THAT THE INLET TEMPERATURE OF THE OXIDIZING GAS PRIOR TO CONTACT WITH THE COMPOSITE IS LESS THAN ABOUT 500*F.
