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.
