    摘要: For the selective production of propylene from an olefinic C4 fraction, a process is implemented that successively comprises: 1) the selective hydrogenation of butadiene with isomerization of butene-1 into butene-2; 2) the separation by distillation of a mixture that is rich in isobutene and butene-1 at the top and a fraction that is rich in butene-2 at the bottom; 3) the skeletal isomerization of isobutene into n-butenes on the top fraction, with recycling in stage 1; and 4) the metathesis of the butene-2-rich fraction with ethylene.

    摘要: Continuous process for the skeletal isomerization of n-olefins containing at the most 20 carbon atoms, in the presence of a catalyst essentially constituted by alumina and titanium, in which a charge containing the said n-olefins is made to flow through at least one fluidized bed reaction zone, the catalyst flowing into each reaction zone. The catalyst drawn off from the final reaction zone is passed into a regeneration zone, at the outlet of which it is passed into a zone where it undergoes a steam treatment prior to its reintroduction into the first reaction zone. The process is performed in the presence of steam, so that the catalyst is in contact with 3 to 85 wt. % (based on the catalyst weight) of steam. The water/olefin charge molar ratio in the reaction zone is between 0.1 and 3.

    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.
