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.

[ What is claimed is:] [1.] A process for the preparation of a catalyst, comprisingintroducing a sulphuration agent into a catalytic mass to introduce an amount of sulfur of 80 to 150% based on the stoichiometric amount of active metals in the catalyst,treating the mass with hydrogen to produce a suifided catalyst, wherein more than 50% of said active metals are present in the form of sulfides,passivating the sulfided catalyst by contacting with an oxygen containing gas. [4.] A process for the preparation of a catalyst, comprisingintroducing a sulphuration agent into a catalytic mass containing active metals which are cobalt, molybdenum, tungsten, or a mixture of cobalt and molybdenum, and optionally platinum or palladium,treating the mass with hydrogen to produce a sulfided catalyst, wherein more than 50% of said active metals are in the form of MoS.sub.2, Co.sub.9 S.sub.8, or WS.sub.2passivating the sulfided catalyst by contacting with an oxygen containing gas.
