    摘要： 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.

    摘要： A catalyst is described for selective gas phase hydrogenation of acetylenic compounds containing 2 or 3 carbon atoms to the corresponding ethylenic compounds. The catalyst, in the form of spherules or extrudates, comprises palladium, at least one metal from group IB, optionally at least one alkali or alkaline-earth metal, and alumina, in which at least 80% of the palladium and at least 80% of the element from group IB are present in a volume at the periphery of the catalyst defined between a spherical or cylindrical surface with radius r.sub.1 corresponding to the average radius of the spherules or extrudates of the catalyst and a spherical or cylindrical surface with radius r.sub.2 at least equal to 0.8 r.sub.1, the catalyst having a group IB metal/palladium ratio of 0.4 to 3 by weight. Further, it is advantageous for this catalyst that at least 30% of the metal particles contain both palladium and silver.

    摘要： A particulate selective hydrogenation catalyst for transforming unsaturated diolefinic hydrocarbons to .alpha.-olefinic hydrocarbons is described, for the hydrogenation of diolefinic compounds to .alpha.-olefinic compounds at rates which are at least 1.5 times higher than the rate of hydrogenation of .alpha.-olefinic hydrocarbons to saturated compounds. The catalyst contains palladium distributed at the periphery of particles (spherules or extrudates), and at least one element selected from tin and lead. Further, the tin and/or lead is advantageously distributed at the periphery of the spherules or extrudates. The catalyst preparation is also described, as well as a process for selective hydrogenation of diolefins to .alpha.-olefins using the catalyst.
