ABSTRACT:
The invention concerns a hydrogenation process, in particular for the selective hydrogenation of diolefins in volatiles produced by steam cracking or other cracking processes, in which the catalyst is distributed in a plurality of beds. It is characterized in that the different catalyst beds are not used at the same time, but successively and in accordance with a given order.
