A process for preparing an improved slurry catalyst for the upgrade of heavy oil feedstock is provided. The process comprises providing at least a metal precursor in solution comprising at least two different metal cations in its molecular structure, with at least one of the metal cations is a Group VIB metal cation; sulfiding the metal precursor with a sulfiding agent in solution forming a catalyst precursor; and mixing the catalyst precursor with a hydrocarbon diluent to form the slurry catalyst. In one embodiment, the at least a metal precursor compri...
1. A process for preparing a slurry catalyst for use in upgrading heavy oil feedstock, comprising: providing a double salt metal precursor comprising at least two different metal cations in its molecular structure, with at least one of the metal cations comprising a Group VIB metal cation;sulfiding the double salt metal precursor with a sulfiding agent forming a catalyst precursor; andmixing the catalyst precursor with a hydrocarbon diluent to form a slurry catalyst having an average particle size of 1-300 μm. 2. The process of claim 1, wherein the mixin...
