Abstract: 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.
