Abstract
A process for preparing a slurry catalyst for the upgrade of heavy oil feedstock is provided. The process employs a pressure leach solution obtained from a metal recovery process as part of the metal precursor feed. In one embodiment, the process comprises: sulfiding a pressure leach solution having at least a Group VIB metal precursor compound in solution forming a catalyst precursor, and mixing the sulfided catalyst precursor with a hydrocarbon diluent to form the slurry catalyst. In another embodiment, the pressure leach solution is mixed with a hydrocarbon diluent under high shear mixing conditions to form an emulsion, which emulsion can be sulfided in-situ upon contact with a heavy oil feedstock in the heavy oil upgrade process.
