    摘要: The present invention provides methods of synthesizing molybdenum disulfide (MoS2) and carbon-containing molybdenum disulfide (MoS2-xCx) catalysts that exhibit improved catalytic activity for hydrotreating reactions involving hydrodesulfurization, hydrodenitrogenation, and hydrogenation. The present invention also concerns the resulting catalysts. Furthermore, the invention concerns the promotion of these catalysts with Co, Ni, Fe, and/or Ru sulfides to create catalysts with greater activity, for hydrotreating reactions, than conventional catalysts such as cobalt molybdate on alumina support.

    摘要: An improved hydroconversion process for carbonaceous materials wherein an ammonium or hydrocarbyl substituted ammonium salt of a metal-sulfur analog of cubane having an anion with a core structure of M.sub.4 S.sub.4 is used as a catalyst precursor. In the general formula, M may be the same or a different metal having hydrogenation catalytic activity when used as a sulfide and capable of occupying one or more vertices in a cubane structure. The metal may also have the capability of bridging one or more such structures. The improved process is effective for both normally solid and normally liquid carbonaceous materials and for carbonaceous materials which are either solid or liquid at the conversion conditions. The hydroconversion will be accomplished at a temperature within the range from about 500.degree. to about 900.degree. F., at a total pressure within the range from about 500 to about 7000 psig and at a hydrogen partial pressure within the range from about 400 to about 5000 psig.

    摘要: A method is described for the preparation of chalcogenides of ruthenium, rhodium, osmium and iridium transition metals of the Periodic Table of the Elements which comprises mixing in the absence of an aqueous solvent a Group VIII transition metal salt with a source of chalcognide, said chalcogenide being selected from the group consisting of sulfur, selenium, tellurium and mixtures thereof, yielding a precipitate of the formula MX.sub.y wherein M is selected from the group consisting of ruthenium, rhodium, and osmium and iridium, X is sulfur, selenium, tellurium and mixtures thereof and y is a number ranging from about 0.1 to about 3, preferably 0.1 to about 2.5. By the practice of the nonaqueous synthesis technique, Group VIII chalcogenides are prepared which are finely divided, have a high surface area, small particle size and small crystallite size which are also free of excess sulfur, water and/or hydrolysis products. Layered stoichiometric osmium disulfide is prepared by this technique. The precipitates may be cleaned of any anion salt coproduct by any technique common to the art.Compounds of the formula MX.sub.y thus prepared are superior sulfur-tolerant catalysts in catalytic processes, for example, hydrodesulfurization, hydrodenitrogenation, hydroconversion, hydrogenation.

    摘要: Sulfides of Group IVb and Vb transition metals are produced by reacting their halides with carbon disulfide. The reactions can be between liquid or gaseous halides and liquid or gaseous carbon disulfide. The reaction products are formed and recovered as solids and the other reaction product, carbon tetrahalide, is carried off as a gas and recovered. A specific example is the production of titanium disulfide by reacting titanium tetrachloride with carbon disulfide.
