  • Dispersed metal sulfide-based catalysts
    Patent number: 8815765
    Abstract: The invention provides a catalyst composition, which includes an emulsion of an aqueous phase in an oil phase, wherein the aqueous phase comprises an aqueous solution containing a group 6 metal and a group 8, 9 or 10 metal. The metals can be provided in two separate emulsions, and these emulsions are well suited for treating hydrocarbon feedstocks.
    Type: Grant
    Filed: February 27, 2012
    Date of Patent: August 26, 2014
    Assignee: Intevep, S.A.
    Inventors: Jose Cordova, Francisco Granadillo, Roger Marzin, Bruno Solari, Luis Zacarias

  • Production of oil soluble catalytic precursors
    Patent number: 6043182
    Abstract: A method for preparing an oil soluble catalytic precursor includes the steps of: providing a mixture of a catalytic metal salt in water, wherein the catalytic metal salt contains a catalytic metal selected from the group consisting of alkali metals, alkaline earth metals, transition metals, and mixtures thereof; providing a heavy hydrocarbon phase; forming a water in oil emulsion of the mixture in the heavy hydrocarbon phase; and heating the emulsion at a temperature sufficient to dehydrate the emulsion so as to provide a hydrocarbon containing an oil soluble compound containing the catalytic metal.
