Abstract
The invention relates to a process for the sulphurization of catalysts for the hydrotreating of hydrocarbon feedstocks. According to the invention, a small amount of at least one orthophthalic acid ester is added to the sulphurization agent used to sulphurize the catalyst. The catalysts thus sulphurized prove to be more active than conventionally sulphurized catalysts.
