Abstract
The invention concerns a reactive distillation apparatus comprising a distillation zone, associated with a reaction zone which is at least in part internal to said distillation zone and comprises at least one catalytic bed in which the feed is transformed in the presence of a catalyst and at least one gas stream containing hydrogen, characterized in that each catalytic bed in the internal portion of said reaction zone is traversed by said gas stream and liquid in ascending co-current mode. The invention also concerns selective hydrogenation processes for light unsaturated hydrocarbons, mainly any olefins and benzene, comprised in a mixture the major portion of which is constituted by hydrocarbons containing at least five carbon atoms per molecule, and the hydroisomerisation of at least a portion of the 1-butene contained in a feed the major portion of which is constituted by olefinic hydrocarbons including isobutene, also 1-butene and 2-butenes in a ratio which substantially corresponds to the thermodynamic equilibrium.
