(57) Abstract
A process for converting a heay hydrocarbon fraction comprises treating the hydrocarbon feed in a hydroconversion
section in the presence of hydrogen, the section comprising at least one three-phase reactor containing at least one
ebullated bed hYdroconversion catalyst, operating in liquid and gas riser mode, said reactor comprising at least one
means for removing catalyst from said reactor and at least one means for adding fresh catalyst to said reactor. At least
a portion of the hydroconverted liquid effluent is sent to at) 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; and at
least a portion of the deasphalted hydrocarbon cut is sent to a hydrotreatment section from which a gas fraction, an
atmospheric distillate and a heavier liquid fraction of the hydro treated feed are produced by atmospheric distillation
separation.
