Abstract: This invention relates to improvements in a process for the preparation of a magnetic catalyst, particularly a magnetic reforming catalyst. In such process, a Group VIII noble metal is incorporated within an inorganic oxide particulate mass, suitably by impregnation of preformed particles. The metal-containing inorganic oxide particulate mass, in the desired proportion, is then admixed with magnetic alloy particles, notably iron or cobalt, and an inorganic oxide precursor which serves as a binder, to form a particulate composite mass comprised of particles of magnetic alloy dispersed as inclusions within an inorganic oxide matrix.

Abstract: A novel catalyst composition, and process for the preparation of magnetic, catalytic composites to improve catalytic metals utilization. A particulate magnetic alloy of iron or cobalt is contacted with a phosphate ion containing solution and reacted therewith sufficiently to form a surface film thereupon, removed from said solution, preferably dried, then admixed or otherwise incorporated within an inorganic oxide matrix, notably alumina, as inclusions, the composite particle is then contacted with a solution which contains a compound, or compounds, of a Group VIII noble metal, notably platinum, which is deposited within the composite particle in catalytically effective amounts without significant loss of the catalytic metal due to surface deposition of the catalytic metal upon said particulate magnetic alloy inclusions.

Abstract: Novel hydrogenation catalysts are formed by impregnating a suitable support material with an aqueous solution of a salt of a transition metal; heat-treating the impregnated support at a temperature above 500.degree. F. to form chemical complexes on the surface of the support and to drive off moisture and absorbed oxygen; activating the surface complex by contacting the impregnated support with a soluble crganometallic compound wherein the metal constituent is selected from Groups I, II and III of the Periodic Chart of the Elements, and thereafter treating the activated support material in the presence of a gaseous stream containing hydrogen at a temperature of at least 300.degree. F. to form a highly stable heterogeneous catalyst. The novel supported catalysts of the instant invention have been found to be highly active for the hydrogenation of organic compounds under extremely mild conditions.

Abstract: A heavy hydrocarbonaceous oil containing a Group IB, IVB, VB, VIB, VIIB or VIII transition metal compound is upgraded by treatment with hydrogen or a hydrogen donor compound in the presence of an aluminum alkyl compound, for example, triethyl aluminum. The transition metal compound may be naturally occurring in the oil or added to the oil. A preferred transition metal compound is vanadyl phthalocyanine.
