Abstract: The apparatus for carrying out reactions in the gaseous, liquid and solid phases comprises a liquid stream-gas compressor for producing a reaction fluid, a reactor charged with metal braiding coated with catalyst, and a feed line. The apparatus for carrying out reactions in the gaseous, liquid and solid phases comprises a liquid stream-gas compressor (6) for producing a reaction fluid by dispersing a gas phase in a liquid phase; a reactor (1) having an inlet and an outlet and a reaction chamber limited by heat-deviating walls, the reactor being charged with a metal braiding coated with catalyst; and a line (7) feeding the reaction fluid from the compressor to the reactor inlet and is short so that the degree of dispersibility of the fluid does not change during the passage through the line. An Independent claim is also included for a process for carrying out reactions in the gaseous, liquid and solid phases comprising producing a reaction fluid by dispersion of a gaseous phase in a liquid phase; feeding the reaction fluid produced through the reactor; exchanging reaction heat on the walls of the reactor chamber; and separating the reaction fluid into a gas phase and a liquid phase.

Abstract: Selective catalytic gas-phase hydrogenation of alkynes, dienes, alkenynes and/or polyenes in an olefin-containing hydrocarbon stream in a series of two or more reaction zones without feeding part of the hydrocarbon stream between the penultimate and last reaction zones. The process comprises adjusting the hydrogen content before the penultimate zone and the conversion in the penultimate zone so that the reaction mixture leaving the penultimate zone contains at least 0.7 vol.% hydrogen.

Abstract: A multistage process for preparing propene, in which the first stage is the reaction of 1-butene, 2-butene and isobutene to give propene, 2-pentene and 2-methyl-2-butene in the presence of a metathesis catalyst comprising at least one compound of a metal of transition group VIb, VIIb or VIII of the Periodic Table of the Elements; the second stage is separation of the propene and 2-pentene/2-methyl-2-butene formed; the third stage is reaction of the 2-pentene and 2-methyl-2-butene with ethehe to give propene, 1-butene and isobutene in the presence of a metathesis catalyst comprising at least one compound of a metal of transition group VIb, VIIb or VIII of the Periodic Table of the Elements; the fourth stage is separation of the propene and 1-butene/isobutene formed and returning the 1-butene and isobutene formed to the first stage.

Abstract: Colloidal palladium for hydrogenating olefins, acetylene, dienes and (un)saturated nitriles consists of palladium clusters having an average particle size of 0.2-2.0 nm. At least 80% of the palladium clusters have a particle diameter which deviates not more than 0.2 nm from the average particle diameter. The clusters have protective ligands on the surface. Independent claims are also included for: (1) production of a palladium colloidal solution by reacting a palladium salt with a reductant made of 4-30 C alcohol, and a protective ligand of phosphane and/or aromatic nitrogen compound at 0-300o C; (2) production of colloidal palladium comprising forming the above palladium colloidal solution, precipitating the colloidal palladium by adding a hydrocarbon solvent, removing the colloidal palladium, and drying; and (3) production of a palladium-containing heterogeneous catalyst by forming the palladium solution as above, impregnating a carrier selected from alumina, silicon dioxide, zirconium dioxide, titanium dioxide, carbon, zeolite and silicate.

Abstract: The production of 5C/6C olefins from a 4C olefin-containing product stream involves disproportionation of 1-, 2- and iso-butene on a Group VIb, VIIb or Sub-Group VIII metal-based catalyst followed by distillation to give a 4-6C fraction which is then distilled to give hexene and methylpentene as a high-boiling fraction. A process (A) for the production of 5C/6C olefins from 4C olefins involves: (a) disproportionation of 1-butene, 2-butene and isobutene in a 4C olefin product stream in presence of a disproportionation catalyst containing Group VIb, VIIb or Sub-Group VIII metal compound(s), to give a mixture of 2-6C olefins and butanes; (b) distillation to give a low-boiling fraction (A) comprising 2-3C olefins or 2-4C olefins and butanes, which is removed, and a high-boiling fraction consisting of 4-6C olefins and butanes; (c) distillation of the high-boiling fraction to give a low-boiling fraction (B; butenes and butanes), a middle fraction (C; pentene and methylbutene) and a high-boiling fraction (D; hexene and methylpentene), and (d) separation of (D) as product, with complete or partial return of fractions (B) and/or (C) to stage (a). An Independent claim is also included for a process (B) for the production of 5C/6C olefins and propene from steam cracker streams or refinery 4C streams, involving: (1) removal of butadiene and acetylenes by optional extraction with a butadiene-selective solvent and subsequent or alternative selective hydrogenation of butadienes and acetylenic impurities in the crude 4C fraction, to give a product containing n-butene and iso-butene; (2) removal of isobutene by reaction of the above product with an alcohol in presence of acid catalyst to give an ether, with separation of the ether and alcohol to give a product containing n-butene and possibly oxygenated impurities, and removal of the ether or re-cleavage for the production of pure isobutene by subsequent distillation with optional separation of entrained 3C, iso-4C and 5C hydrocarbons; (3) removal of oxygenated impurities on suitable adsorbers; and (4) disproportionation of the refined product (II) stream as in stages (a)-(d) above.
