A method for preparing an improved slurry catalyst for the upgrade of heavy oil feedstock is provided. In one embodiment, the process comprises: sulfiding at least a metal precursor solution with at least a sulfiding agent forming a sulfided Group VIB catalyst precursor, the metal precursor solution having a pH of at least 4 and a concentration of less than 10 wt. % of Primary metal in solution; and mixing the catalyst precursor with a hydrocarbon diluent to form the slurry catalyst composition. The slurry catalyst prepared therefrom has a BET total surf...
1. A process for preparing a slurry catalyst for use in the upgrade of heavy oil feedstock, comprising: providing a metal precursor solution comprising at least a water soluble salt of a Primary metal selected from any of a Group VIB metal and a Group VIII metal in a water diluent, the metal precursor solution having a pH of at least 4 and a concentration of less than 10 wt. % of the Primary metal in solution;providing a metal precursor solution comprising at least a water-soluble salt of a Promoter metal selected from any of Group IVB metals, Group VIII...
