Abstract
Hydrogenation of a liquid cut containing hydrocarbons, in particular unsaturated molecules containing at least two double bonds or at least one triple bond, is described wherein the unsaturated molecules are at least partially hydrogenated to less unsaturated molecules containing at least one double bond, in at least one reactor comprising at least two distinct beds of at least one hydrogenation catalyst, and wherein a gas phase containing hydrogen is introduced, a portion thereof being mixed with said cut upstream of the first catalyst bed and a portion thereof being introduced upstream of the subsequent beds contained in said reactor.
