The invention relates to a reactive distillation device comprising a zone of distillation, associated with a reaction zone at least partially internal to said distillation zone and comprising at least one catalytic bed, in which the conversion of the charge is carried out, in the presence of a catalyst and at least a gas stream comprising hydrogen, characterized in that all reads catalytic of the internal part of said reaction zone is crossed in ascending cocurrent by said gas flow and the liquid. The invention also relates to processes for the selective hydrogenation of light unsaturated hydrocarbons, mainly possible olefins and benzene, included in a mixture consisting mainly of hydrocarbons containing at least five atoms of carbon per molecule, as well as hydroisomerization of at least part of the butene-1 included in a charge comprising mainly of olefinic hydrocarbons including isobutene, butene-1 and butenes-2 in relation corresponding substantially to the thermodynamic equilibrium. |
