An improved process for preparing a slurry catalyst for the upgrade of heavy oil feedstock is provided. In the process, high shear mixing is employed to generate an emulsion containing droplets of metal precursor in oil with droplet sizes ranging from 0.1 to 300 μm. The emulsion is subsequently sulfided with a sulfiding agent, or in-situ in a heavy oil feedstock to form a slurry catalyst. The in-situ sulfidation in heavy oil is under sufficient condition for the heavy oil feedstock to generate the sulfiding source needed for the sulfidation.

1. A process for preparing a slurry catalyst for use in upgrading heavy oil feedstock, comprising: providing a metal precursor solution comprising a mixture of at least two different water-soluble metal salts in a water solvent of at least two different metals selected from Group VIB, Group VIII, Group IVB, Group IIB metals and mixtures thereof;mixing the metal precursor solution with a hydrocarbon diluent under high shear mixing to generate an emulsion with droplet sizes ranging from 0.1 to 300 μm;sulfiding the emulsion with at least a sulfiding agent to form the slurry catalyst having an average particle size ranging from 1 to 300 μm. 2. The process of claim 1, further comprising: subjecting the emulsion to reduction in the presence of a reducing agent at a temperature above ambient. 3. The process of claim 1, wherein the emulsion is mixed with the heavy oil feedstock in a reactor under in-situ sulfiding condition for the heavy oil feedstock to provide the sulfiding agent needed for to sulfide the emulsion forming the slurry catalyst. 4. The process of claim 3, wherein the in-situ sulfiding condition is at a temperature from 752 ° F. to 1112 ° F. and a pressure from 1435 psig (10 MPa) to 3610 psig (25 MPa). 5. The process of claim 1, where the sulfidation of the emulsion forming the slurry catalyst occurs ex-situ prior to the heavy oil upgrade. 6. The process of claim 5, wherein the sulfiding agent is selected from the group of elemental sulfur, hydrogen sulfide, ammonium sulfide, ammonium polysulfide ((NH4)2Sx), ammonium thiosulfate ((NH4)2S2O3), sodium thiosulfate (Na2S2O3), thiourea (CSN2H4), carbon disulfide, dimethyl disulfide (DMDS), dimethyl sulfide (DMS), tertiarybutyl polysulfide (PSTB) and tertiarynonyl polysulfide (PSTN), and mixtures thereof. 7. The process of claim 5, wherein the hydrocarbon diluent is selected from gasoline, diesel, vacuum gas oil (VGO), cycle oil (MCO or HCO), jet oil, fuel oil, heavy oil feedstock, and mixtures thereof. 8. The process of claim 5, further comprising subjecting the slurry catalyst after ex-situ sulfidation to reduction at a temperature above ambient. 9. The process of claim 1, wherein the emulsion precursor comprises droplets having a size of less than 100 μm. 10. The process of claim 1, wherein the emulsion droplets contain metal precursor solution in a hydrocarbon diluent. 11. The process of claim 1, wherein the emulsion droplets contain hydrocarbon diluent in a metal precursor solution. 12. The process of claim 1, wherein the slurry prepared therefrom has a general formula (Mt)a(Lu)b(Sv)d(Cw)e(Hx)f(Oy)g(Nz)h, wherein M is a Primary metal selected from group VIB metals, Group VIII metals, Group IIB metals; L is optional as a Promoter metal and L is different from M, L is at least one of a Group VIII metal, a Group VIB metal, a Group IVB metal, and a Group IIB metal; b >=0; 0==0; 0=
