ABSTRACT:
Disclosed are the preparation of a sulfided catalyst and the use of said catalyst in the hydrotreatment of hydrocarbon feeds. The sulfidation is carried out by ex situ presulfiding of a fresh or regenerated catalyst, followed by the resulting material being contacted in situ at elevated temperature with hydrogen gas in combination with either a sulfiding agent, e.g., hydrogen sulfide, or a spiked feed.
