(57)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 hydro treated 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 I
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 i de asp halted hydrocarbon cut is sent to a
hydrotreatment section from which a gas fraction, a fuel fraction and a heavier liquid fraction of the hydro treated
feed are recovered, and at least a portion of the heavier liquid fraction of the hydrotreated teed 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.
