ABSTRACT:
A process for converting a heavy hydrocarbon fraction comprises treating the hydrocarbon feed in a hydrodemetallization section, the section containing at least one fixed bed hydrodemetallization catalyst. At least a portion of the hydrotreated liquid effluent from step a) is sent to an atmospheric distillation zone from which a distillate and an atmospheric residue are recovered; at least a portion of the atmospheric residue is sent to a vacuum distillation zone from which a vacuum distillate and a vacuum residue are recovered; at least a portion of the vacuum residue is sent to a deasphalting section from which a deasphalted hydrocarbon cut and residual asphalt are recovered; at least a portion of the deasphalted hydrocarbon cut is sent to a hydrotreatment section from which a gas fraction, a fuel fraction and a heavier liquid fraction of the hydrotreated feed are recovered, and at least a portion of the heavier liquid fraction of the hydrotreated feed is sent to a catalytic cracking section in which it is treated under conditions such that a gaseous fraction, a gasoline fraction, a gas oil fraction and a slurry fraction are produced.
