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.

Dispersed metal sulfide-based catalysts

A hydroconversion process includes feeding a heavy feedstock containing vanadium and/or nickel, a catalyst emulsion containing at least one group 8-10 metal and at least one group 6 metal, hydrogen and an organic additive to a hydroconversion zone under hydroconversion conditions to produce an upgraded hydrocarbon product and a solid carbonaceous material containing the group 8-10 metal, the group 6 metal, and the vanadium and/or nickel.

Hydroconversion process for heavy and extra heavy oils and residuals

A process for steam conversion of a hydrocarbon feedstock in the presence of a catalyst includes the steps of (a) providing a catalytic emulsion comprising a water in oil emulsion containing a first alkali metal and a second metal selected from the group consisting of Group VIII non-noble metals, alkaline earth metals and mixtures thereof; (b) mixing the catalytic emulsion with a hydrocarbon feedstock to provide a reaction mixture; and (c) subjecting the reaction mixture to steam conversion conditions so as to provide an upgraded hydrocarbon product. A catalytic emulsion and process for preparing same are also provided.

Steam conversion process and catalyst

A process for separating finely divided solid particles from a hydroprocessing liquid product which comprises treating a heavy hydrocarbon feed having an asphaltene content of at least 1 wt. % so as to obtain an unstable product characterized by heavy molecular weight molecules which promote the agglomeration of said finely divided solid particles and thereafter feeding said unstable product to a precipitating zone provided with a centrifugal decanter for precipitating the agglomerated solid particles and said heavy molecular weight molecules in said precipitating zone wherein at least 80 wt. % of the finely divided solid particles is recovered.

Process for solid separation from hydroprocessing liquid product

The present invention is drawn to a process for the production of anode grade coke from a hydrocarbon feed characterized by high levels of sulfurs and metals. The hydrocarbon feed is hydrocracked in a hydrocracking reactor so as to produce an overhead effluent which is fed to a hot separator wherein a light hydrocarbon stream and a slurry hydrocracked product are produced. The hydrocracked product is fed to a separator and mixed with a solvent wherein the solids are separated out from the hydrocracked residual so as to produce a clean hydrocracked residual which is fed to a coking drum and coked so as to leave a mass of green anode grade coke.

Process for producing anode grade coke employing heavy crudes

Hydrocracking and separating process for upgrading unconverted residuals so as to increase liquid yields while at the same time decrease fouling of the hydrocracking reactor upon recycling of the upgraded residual to the hydrocracker. The unconverted residual from the hydrocracking unit is treated in a separation stage with a light hydrocarbon solvent so as to remove the polynuclear hydrocarbons from the residual prior to recycling.
