Abstract:
A process for converting a hydrocarbon feed in which said feed is treated in a distillation zone producing an overhead vapour distillate and a bottom effluent, associated with an at least partially external reaction zone and comprising at least one catalytic bed, in which at least one reaction for converting at least a portion of at least one hydrocarbon is carried out in the external presence of a catalyst and a gas stream comprising hydrogen, the feed for the reaction zone being drawn off at the height of at least one draw-off level and representing at least a portion of the liquid flowing in the external distillation zone, at least part of the effluent from the reaction zone being re-introduced into the distillation zone at the height of at least one re-introduction level, so as to ensure continuity of distillation, said process being characterized in that a liquid distillate is withdrawn from the distillation zone at the height of at least one withdrawal level, said level being located below the vapour distillate withdrawal level.
