    摘要： 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 hydroisomerization reaction zone, the bottom product of the distillation zone comprising butene-2 compoundw being passed into a second distillation zone (4), preferably an extractive distillation zone, to obtain a first effluent comprising butene-2 compounds as its major portion and a second effluent comprising normal-butane as its major portion, the major portion of the first effluent being passed into a skeletal isomerization zone (2) where the linear butenes are at least partially isomerized to isobutene, at least part of the principal effluent from the skeletal isomerization zone being recycled upstream of the reactive distillation zone (1).

    摘要： For obtaining butene-1 from butene-2, a charge containing at least one of the isomers of butene-2 is introduced into a distillation zone linked to a hydro-isomerization zone. Part of the effluent from the bottom of the distillation column is removed from the distillation zone, heated in a heat exchanger and passed into an external hydro-isomerization zone. The hydro-isomerization effluent is removed from the hydro-isomerization zone, cooled in a heat exchanger, and then reintroduced into the distillation zone. Effluent containing butene-1 is withdrawn from the top of the column of the distillation zone.

    摘要： The invention provides a process for converting hydrocarbons in which said feed is treated in a distillation zone associated with a reaction zone, the feed for the reaction zone being drawn off at the height of at least one draw-off level, the effluent from the reaction zone being re-introduced into the distillation zone at the height of a re-introduction level, said process being characterized in that a liquid effluent is also withdrawn from the distillation zone at the height of a withdrawal level, said liquid effluent being treated in a gas-liquid side separation zone (splitter), the gaseous effluent being re-introduced into the distillation zone and the liquid effluent being recovered as an intermediate cut. This process can be used to reduce the benzene content of a hydrocarbon cut and to recover a naphtha cut.
