ABSTRACT:
The invention relates to a process for producing high purity isobutene from a hydrocarbon cut essentially comprising olefinic hydrocarbons containing 4 carbon atoms per molecule including isobutene, also butene-1 and butene-2 compounds in a ratio which substantially corresponds to the thermodynamic equilibrium. The process comprises passing the cut into a distillation zone (3) associated with a hydroisomerisation reaction zone, the bottom product of the distillation zone comprising butene-2 compounds being passed into a skeletal isomerisation zone (2) where the linear butenes are at least partially isomerised to isobutene, at least part of the principal effluent from the skeletal isomerisation zone being recycled upstream of the reactive distillation zone (3).
