Abstract
For converting hydrocarbons: step a) treating a hydrocarbon feed with hydrogen in at least one three-phase reactor (1), containing ebullated bed hydroconversion catalyst; a step b) passing effluent from step a) to a separation zone (2) to recover a fraction F1 containing at least a portion of gas, gasoline and atmospheric gas oil contained in the effluent from step a), and a fraction F2 containing compounds with boiling points of more than that of the atmospheric gas oil; step c) hydrodesulphurizing at least a portion of fraction F1; and step d) passing at least a portion of fraction F2 to catalytic cracking section (6).
