    Abstract: A process for production, from an olefinic C4 fraction, on the one hand, of high-purity isobutene and, on the other hand, of propylene by metathesis is described. The process comprises three successive stages: 1) the selective hydrogenation of butadiene with isomerization of butene-1 into butene-2 up to thermodynamic equilibrium; 2) the separation by isobutene at the column head that integrates the hydroisomerization of n-butenes, allowing a butene-2 fraction at the bottom, and 3) the metathesis of the butene-2 fraction with ethylene. By this process, it is possible to produce in a very selective way high-purity isobutene and polymerization-quality propylene.

    Abstract: The invention provides 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 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 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 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level, so as to ensure continuity of the distillation, said process being characterized in that a liquid distillate is withdrawn from the distillation zone at the height of at least one withdrawal level, said level being located below the vapour distillate withdrawal level. This process can be used to reduce the benzene content in a hydrocarbon cut.
