Abstract: 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. The advantage of this process is to produce in a very selective way polymerization-quality propylene from all of the olefinic compounds of a C4 fraction, including isobutene.

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: A process for carrying out a reaction on an organic feed, for example dimerization, co-dimerization, oligomerization or metathesis of olefins, as described in which the catalyst is a catalytic metal compound dissolved in a non-aqueous ionic medium which is not or is only slightly miscible with hydrocarbons. The reaction is carried out in a system comprising at least two treatment loops each comprising at least one reaction zone and at least one zone for separating the organic and polar phases between which the polar medium containing the catalytic metal compound, and the organic phase circulate. Fresh polar phase is injected into the second loop and used polar phase is eliminated from the first loop. The hydrocarbon to be transformed is injected into the first loop and the products are withdrawn from the second loop. The invention also concerns a unit for carrying out the process.

Abstract: The present invention provides a catalyst and a process for metathesis of olefinic C4 cuts. The catalyst contains rhenium, caesium and delta alumina. The preferred catalyst contains at least one rhenium compound deposited on a support principally composed of alumina, treated at a temperature of more than 750° C., and modified by at least one caesium compound. Thus the duration of the cycle between two regeneration operations is substantially increased. Application to a process for the production of propylene from an olefinic C4 cut in three steps: selective hydrogenation of butadiene with isomerisation of 1-butene to 2-butene, separation by distillation of the major portion of the isobutene, and metathesis of the cut rich in 2-butene with ethylene.
