Estimating the term…
Organic compounds are dehydrogenated by contact with a catalyst prepared by oxidizing and then sulfiding a composition comprising Group VIIIA (first or second row) catalytic metal on a nonacidic porous support, for example alumina, to produce compositions which have good dispersion of a catalytically active metal component and of sulfide species over the surface of the compositions and high activity as catalysts for the dehydrogenation of organic compounds. In one embodiment of the invention the catalyst used in the process of the invention has ratios of nickel, and/or sulfide species to peak areas of aluminum in the support, as determined by X-ray photoelectron spectroscopy (XPS), which improve their activity and stability for use as dehydrogenation catalysts. The catalyst may also have ratios of cesium, added to reduce acidity, to aluminum peak areas, as determined by XPS, which have advantages for use as dehydrogenation catalysts in respect of activity, resistance to deactivation and avoidance of side reactions.
