Abstract
An improved process to make a slurry catalyst for the upgrade of heavy oil feedstock is provided. The sulfiding of the metal precursor/catalyst precursor is carried out at least twice (“enhanced sulfiding”) in the improved process to form a slurry catalyst with improved surface area and porosity value. The slurry catalyst under an enhanced sulfiding scheme is characterized as having increased catalytic activities over a slurry catalyst without an enhanced sulfidation step.
