ABSTRACT:
For the treatment of a feed comprising a major portion of olefinic hydrocarbons containing 4 carbon atoms per molecule, including isobutene, 1-butene and 2-butenes in a ratio which substantially corresponds to the thermodynamic equilibrium, in which the feed is treated in a distillation zone comprising a stripping zone and a rectification zone associated with at least one hydroisomerization reaction zone, the hydroisomerization reaction zone being at least partially internal to the distillation zone and comprising at least one catalytic bed, in which hydroisomerization of at least a portion of 1-butene is carried out in the presence of a hydroisomerization catalyst and at least one gas stream comprising hydrogen, such that an effluent rich in isobutene leaves the distillation zone overhead and an effluent rich in 2-butenes leaves the bottom, the process being characterized in that each catalytic bed in the internal portion of the hydroisomerization zone is traversed by an ascending co-current of the gas stream and liquid and is substantially out of contact with the distillation vapor.
