ABSTRACT:
A process comprising incorporation of a sulphuration agent into a hydrocarbon treatment catalyst to a greater or lesser extent into the pores of the catalyst, the agent being selected from, for example, elemental sulphur and organic polysulphides, incorporation being effected in the presence of a solvent which is an olefinic or olefinic cut constituent, for example a vegetable oil, or a similar constituent, the process comprising hydrogen treatment of the catalyst at between 150.degree. C. and 700.degree. C., followed by a passivation step.
