Abstract
The invention concerns a process for converting a hydrocarbon fraction with a sulphur content of at least 0.1% by weight, an initial boiling point of at least 340° C. and an end point of at least 440° C., characterized in that it comprises the following steps:a) treating the hydrocarbon feed in a treatment section in the presence of hydrogen, said section comprising at least one three-phase reactor, containing at least one ebullated bed hydroconversion catalyst and operating in liquid and gas upflow mode;b) sending at least a portion of the effluent from step a) to a section for eliminating catalyst particles contained in said effluent;c) sending at least a portion of the effluent from step b) to a treatment section, treatment being carried out in the presence of hydrogen and optionally a hydrocarbon fraction from a fixed bed hydrotreatment step.
