Summary:The invention relates to a method for converting a heavy charge of hydrocarbons comprising the following steps: a) at least one step of selective deasphalting of the heavy charge of hydrocarbons by liquid/liquid extraction which would allow for the separation of at least one asphalt fraction, at least one deasphalted oil fraction, b) a stage of hydroconversion of the deasphalted oil fraction in the presence of hydrogen in at least one three-phase reactor, under conditions allowing for the obtention of an effluent comprising a gaseous fraction mainly containing the H2 and H2S compounds, and a liquid fraction with a reduced amount of Conradson carbon, metals, sulfur and nitrogen, c) a step for separating the effluent from step b) to obtain a gaseous fraction mainly containing the H2 and H2S compounds and a liquid fraction reduced in Conradson carbon, metals, sulfur and nitrogen.
