1,154,029. Oxydehydrogenation catalyst. STANDARD OIL CO. 9 June, 1966 [10 June, 1965], No. 25829/66. Heading B1E. [Also in Division C5] A catalyst for the oxydehydrogenation of C 4 to C 10 monoolefins to conjugated dienes has the composition A a B b Fe c Bi d P e Mo f O 2 , where A is Group VIII transition metal other than Fe, B is at least one of Sb, Sn, Cu and As, and a is 0.1 to 12, b is 0 to 12, c is 0.1 to 12, d is 0.1 to 12, e is 0 to 12, f is 6 to 12, and the Mo@ may be at least partially replaced by W. The catalyst may be used alone or on a carrier material, for example silica, alumina, thoria, zirconia, titania, boron phosphate, silicon carbide, pumice, diatomaceous earth or clay ,the carrier being used in amount less than 95% by weight of the final catalyst composition. The catalysts may be made by dissolving soluble salts of the metals in water or acid and heating the mixture with an aqueous silica dispersion until a gel forms. The gel is heated to dry it then calcined in air. |
