Abstract (en)
[origin: WO2019121073A1] The invention concerns a method for converting a heavy hydrocarbon feedstock containing a fraction of at least 50% having a boiling temperature of at least 300°C and containing sulfur, Conradson carbon, metals and nitrogen, comprising at least two successive hydroconversion steps, that may be separated by an intermediate separation step, and at least one step of deasphalting a heavy fraction of the effluent from the hydroconversion, at least part of the deasphalted oil (DAO) being recycled during the hydroconversion, downstream from the first hydroconversion step. The DAO is either recycled upon exiting the deasphalter, or after having undergone a fractionation step producing a heavy fraction of the DAO that then constitutes the recycled part of the DAO. This method helps simultaneously improve the level of conversion and the stability of the liquid effluents.
