    摘要： A process for treating a feed comprising C.sub.5.sup.+ hydrocarbons and comprising at least one unsaturated C.sub.6.sup.+ compound including benzene, is such that the feed is treated in a distillation zone, associated with a hydrogenation zone, comprising at least one catalytic bed, in which the hydrogenation is carried out of unsaturated C.sub.6.sup.+ compounds contained in the feed, and whereof a charge for the hydrogenation step is removed at the height of a removal level and represents at least part of the liquid flowing in the distillation zone, and the effluent from the hydrogenation reaction zone is at least in part reintroduced into the distillation zone to ensure continuity of the distillation operation, the effluents at the top and bottom on the distillation zone being very depleted of unsaturated C.sub.6.sup.+ compounds. The effluent drawn off from the top of the distillation zone is treated in a zone for the isomerisation of C.sub.5 and/or C.sub.6 paraffins.
