A process for treating a hydrocarbon feed having a sulfur content of at least 0.5 wt.%, An asphaltene content of at least 1 wt.%, An initial boiling temperature of at least 1 wt. 340 ° C and a final boiling point of at least 480 ° C, to obtain at least one deasphalted oil fraction having a sulfur content of less than or equal to 0.5% by weight and a lower sediment content or equal to 0.1% by weight, comprising the following successive stages: a) a hydrotreating step, b) optionally a separation step of the effluent obtained at the end of step a), c) a step hydroconversion of at least a portion of the effluent from step a) or at least a portion of the heavy fraction from step b) and optionally at least a portion of the light fraction from step b), d) a step of separating the effluent from step c), e) at least one step of disasphon selective alteration of at least a portion of the liquid hydrocarbon fraction resulting from step d), f) a step of recycling at least a portion of said unsaturated oil fraction from step e) upstream of the step a) of hydrotreatment and / or at the entry of the hydroconversion stage c). |
