    摘要： A process for converting a heavy 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 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; 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 hydrotreated feed are produced by atmospheric distillation separation.

    摘要： A treatment of highly viscous and very dense oils at the oil field to effect their desalting, and resulting in the production of an easily transportable hydrocarbon mixture of reduced viscosity, comprising the steps of:(a) diluting the crude oil with a hydrocarbon cut obtained in step (d);(b) subjecting the effluent from step (a) to a desalting-dehydration treatment;(c) subjecting the effluent from step (b) to hydrovisbreaking; and(d) distilling the effluent from step (c), and recycling a hydrocarbon cut to step (a), the remaining part forming a synthetic crude oil of reduced viscosity.
