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: 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.
