    (54) Process for the conversion of a residual hydrocarbon oil


    (57) Process for the conversion of a residual hydrocarbon oil, preferably a vacuum hydrocarbon oil residue, comprising the following steps:

    (a) deasphalting the residual hydrocarbon oil producing an asphaltic fraction and a deasphalted oil (DAO);

    (b) passing the DAO through a bed of a hydrodemetallisation catalyst in the presence of hydrogen under demetallising conditions, producing an upgraded DAO; and

    (c) blending the upgraded DAO with one or more flashed distillate fractions and subjecting the resulting blend stream to hydrocracking, producing one or more distillate fractions.
