    Abstract: Process for forming multi-component oxide catalysts. According to the invention the key catalytic phase of the catalyst is preformed and the elements of the host-catalyst phase are added together or separately. The key catalytic phase contains a molybdate or a tungstate of Bi, Te, Sb, Sn Cu or mixtures thereof. A representative catalyst is 50% [Bi2Mo3O12] 1/2 [K0.1Ni2.5Co4.5Fe3P0.5Mo10.5 Ox] + 50% SiO2 In the production of this catalyst a preformed bismuth molybdate slurry is added to a host-catalyst slurry. The mixture was then dried, calcined, ground and calcined once again.

    Abstract: PROCESS FOR THE PREPARATION OF DIOLEFINS FROM OLEFINS A catalyst is disclosed wherein the atomic ratios are disclosed by the empirical formula: Aa Cc Dd Fee Bif Mog Ox wherein A is chromium, tellurium, germanium, tungsten, manganese, thorium, niobium, praseodymium, cerium, lanthanum, zinc or mixture thereof; C is an alkali metal, alkaline earth metal, Tl, In, Ag, Cu, Sn, Sb, rare earth metal or mixture thereof; D is nickel, cobalt, magnesium, zinc, cadmium, manganese, calcium or mixture thereof; A is not the same as D; and wherein a is greater than zero to about 4; c is 0 to about 4; d is 0.1 to about 20; e and f are 0.01 to 12; g is 10 to 15; and x is the number of oxygens required by the valence states of the other elements present. This catalyst may be employed for the oxidative dehydrogenation of olefins of 1 to about 10 carbon atoms.

    Abstract: Catalysts comprising the combined oxides of vanadium and at least one element selected from the group consisting of boron, niobium, tantalum, antimony, tungsten and chromium have been found to be especially effective in the oxidation of n-butane, n-butenes and butadiene, or a mixture thereof with molecular oxygen in the vapor phase to yield maleic anhydride. The catalysts of the present invention may be further promoted with additional elements to enhance activity, stability and selectivity. The reaction with n-butane gives an especially pure product in good yield and selectivity.
