  • Patent number: 4101560
    Abstract: Disclosed is a shaped catalyst composed of finely divided particles of binary or ternary boride compounds having the general formula M.sub.x B.sub.y or M.sub.x B.sub.y R.sub.2 wherein x is an integer from 1-5; y is an integer from 1-2; z is an integer from 1-4; B is boron; M is an element selected from the groups II-A, III-B, IV-B, V-B, VI-B, VII-B, VIII, III-A, IV-A, and V-A of the Periodic Table, the rare earths, and the actinides; R is an element different from M selected from the same group of elements in the Periodic Table as M; the particles being bonded by 1 to 10% by weight of finely divided particles of preoxidized aluminum, zinc, or magnesium. The preferred catalyst materials are those boron-containing substances which are substantially insoluble in the reaction mixture containing the organic hydroperoxides olefins and products and which are bonded by heat treated aluminum particles having an oxide coating constituting from 5 to 10 percent of the particles.

  • Patent number: 4083800
    Abstract: A process for the alkylation of alkanes with olefins under alkylation conditions employing a regenerated catalyst having improved activity. The regenerated catalyst is prepared by contacting a deactivated chlorided alumina catalyst in a non-oxidizing atmosphere at a temperature between 400.degree. and 1200.degree. F., thereafter contacting said catalyst in an oxidizing atmosphere at a temperature between 700.degree. and 1200.degree. F. and subsequently rechloriding said catalyst at a temperature between 200.degree. and 800.degree. F.

  • Patent number: 4066716
    Abstract: A process for the alkylation of alkanes with olefins under alkylation conditions with a catalyst having improved long term activity and composed of alumina and chlorine. The improved catalyst is prepared by contacting a catalytically active chlorided alumina composite catalyst with vaporized aluminum chloride to add 2-15 wt. % of additional chlorine to said catalyst. In a preferred embodiment the active catalyst is heat treated in an oxidizing atmosphere prior to contacting with aluminum chloride.
