ABSTRACT OF THE DISCLOSURE Improved process for the hydrodesulphurization of vanadium and nickel-containing residual hydrocarbon oils by contacting the oils successively with two different catalysts each of which has a porosity and particle size within specified ranges depending on the porosity of the other catalyst in the combination and on the applied hydrogen partial pressure and that the catalysts are applied in a given volume ratio. The improvement consists in the fact that the desulphurization is preceded by a hydrodemetallization over a catalyst having a porosity and particle size within specified limits depending among others on the porosity and particle size of the first desulphurization catalyst.
