An additive for hydroconversion processes includes a solid organic material having a particle size of between about 0.1 and about 2,000 &#x3bc;m, a bulk density of between about 500 and about 2,000 kg/m3, a skeletal density of between about 1,000 and about 2,000 kg/m3 and a humidity of between 0 and about 5 wt %. Methods for preparation and use of the additive are also provided. By the use of the additive of the present invention, the hydroconversion process can be performed at high conversion level.

Additive for hydroconversion process and method for making and using same

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 metal recovery process for heavy effluent from a hydroconversion process. The effluent contains unconverted residue and a solid carbonaceous material containing group 8-10 metal, group 6 metal, and vanadium and/or nickel, and the metals are recovered according to the invention.

Metal recovery from hydroconverted heavy effluent

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.
