K 5271 A B S T R A C T A process for the catalytic hydrodesulphurization of heavy hydrocarbon oils, in which process a vanadium- containing heavy hydrocarbon oil is contacted at elevated temperature and pressure and in the presence of hydrogen with a catalyst which contains one or more metals having hydrogenative activity, supported on a carrier, until the average vanadium content of the catalyst has increased by at least 5 parts by weight (vanadium content of the catalyst expressed as parts by weight of vanadium per 100 parts by weight of carrier), after which the hydrodesulphurization is continued in the presence of a quantity of water vapour corresponding with a water vapour partial pressure during the process of 0.5-30 bar.
