Abstract
The invention provides a process for converting hydrocarbons in which said feed is treated in a distillation zone associated with a reaction zone, the feed for the reaction zone being drawn off at the height of at least one draw-off level, the effluent from the reaction zone being re-introduced into the distillation zone at the height of a re-introduction level, said process being characterized in that a liquid effluent is also withdrawn from the distillation zone at the height of a withdrawal level, said liquid effluent being treated in a gas-liquid side separation zone (splitter), the gaseous effluent being re-introduced into the distillation zone and the liquid effluent being recovered as an intermediate cut. This process can be used to reduce the benzene content of a hydrocarbon cut and to recover a naphtha cut.
