Abstract: The invention concerns a method of obtaining, from the cracked gases emerging from a steam cracker, a polymerizable fraction of recyclable material consisting of styrene, methylstyrenes, vinyltoluenes, indene, methylindenes and fractions whose boiling points lie between those of styrene and the methylindenes, a secondary stream from the cracked-gas column being divided, by means of a distillation unit, into the fraction of recyclable material and into fractions which are fed back to the cracked gas column.

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.
