摘要:
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.

This invention relates to a catalyst for hydrorefining and/or hydroconversion of hydrocarbon-containing feedstocks that contain compounds whose boiling point is higher than 520° C. and that contain sulfur and possibly metals, as well as its use in hydrorefining and/or hydroconversion processes of heavy feedstocks. A petroleum residue of atmospheric distillation (RA) or of vacuum distillation (RSV) or a deasphalted oil (DAO) are representative feedstocks of the feedstocks treated within the scope of this invention.
