Process for converting a heavy hydrocarbon feedstock with initial boiling point of at least 300&#xb0; C. comprising: a) hydroconverting at least part of said feedstock; b) separating the effluent from stage a) to obtain light and heavy liquid fractions; c) at least two stages of deasphalting in series at least part of the heavy liquid fraction originating from stage b), allowing to separate at least one fraction of asphalt, at least one fraction of heavy deasphalted oil (heavy DAO) and at least one fraction of light deasphalted oil (light DAO), at least one deasphalting stage being carried out using a mixture of at least one polar solvent and at least one apolar solvent, said deasphalting stages being under subcritical conditions of the mixture of solvents; d) recycling at least part of said heavy deasphalted oil cut from stage c) upstream of hydroconverting a) and/or of the inlet of separating b).

Process for the conversion of a heavy hydrocarbon feedstock integrating selective cascade deasphalting with recycling of a deasphalted cut

The invention concerns a process for refining a heavy hydrocarbon feed, comprising the following steps: a) a step for selective deasphalting of the heavy hydrocarbon feed by single-step liquid/liquid extraction in an extraction medium, said extraction being carried out using a mixture of at least one polar solvent and at least one apolar solvent, in order to obtain an asphalt phase and a deasphalted oil phase DAO, the proportions of said polar solvent and said apolar solvent in the solvent mixture being adjusted as a function of the properties of the feed and the desired asphalt yield, said deasphalting step being carried out under subcritical conditions for the solvent mixture;b) a step for hydrotreatment of at least a portion of the deasphalted oil phase DAO obtained from step a);c) optionally, a step for catalytic cracking of at least a portion of the effluent obtained from step b).

Process for refining a heavy hydrocarbon feed using a selective deasphalting step

The invention relates to a process for refining a heavy feedstock of the vacuum residue type. Selective deasphalting of the feedstock is conducted in a single-stage liquid/liquid extraction in an extractant. Extraction is carried out by means of a mixture of at least one polar solvent and at least one apolar solvent, to obtain an asphalt phase and a deasphalted oil (DAO) phase. The proportions of polar solvent and apolar solvent in the solvent mixture are adjusted according to properties of the feedstock, desired yield of asphalt and/or desired quality of the DAO. Deasphalting is implemented under subcritical conditions. At least a part of the DAO is subjected to hydrotreatment. At least a part of the effluent originating from the hydrotreatment is subjected to catalytic cracking in at least one fluidized-bed reactor under conditions allowing a gasoline fraction and/or a light olefins fraction to be produced.
