METHOD FOR PRE-SULPHURATION OF CATALYSTS

摘要

For the presulphurization of catalysts based on metal oxides, intended especially for the hydrotreating of hydrocarbon feedstocks, at least one tertiary mercaptan (for example tert-dodecyl mercaptan) is employed as sulphurizing agent.This tertiary mercaptan can be employed alone or combined with another sulphur-donor compound.The presulphurization according to the invention may be carried out in situ or ex situ.
