Abstract

A process for making an improved slurry catalyst for the upgrade of heavy oil feedstock is provided. In the process, a metal precursor solution comprising at least a water-soluble molybdenum compound and a water-soluble metal zinc compound is mixed under high shear mixing conditions to generate an emulsion. The emulsion is subsequently sulfided with a sulfiding agent ex-situ, or in-situ in a heavy oil feedstock to form the 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.
