Abstract
Process for treatment of a feedstock, such as hydrocarbons that comprise at least 4 carbon atoms per molecule and that comprise at least one unsaturated compound including benzene, such that said feedstock is treated in a distillation zone, associated with a hydrogenation reaction zone, at least in part outside of the distillation zone, and an isomerization zone, so as to discharge—at the top of the distillation zone and at the bottom of the distillation zone—an effluent that is low in unsaturated compounds, whereby said process comprises the treatment of at least a second feedstock, comprising at least one unsaturated compound including benzene, at least partially directly injected into the hydrogenation zone that is outside of the distillation zone.
