    摘要： The invention relates to a distillation and reaction device having a reaction section and a distillation-reaction section. The distillation-reaction section has a distillation zone with at least one device for circulation of the effluent from the reaction section to the distillation zone. Effluent from the reaction section is circulated to the distillation zone. The distillation-reaction section also has at least one distillation-reaction zone having at least one catalyst bed. The distillation-reaction zone is distinct from the distillation zone and provides at least partly the reflux of the distillation zone. The distillation-reaction section can also have at least one complementary reaction zone containing at least one catalyst bed. The invention further relates to a process for preparing at least one aliphatic monoalcohol, generally in excess, and at least one olefin.

    摘要： The invention concerns a reactive distillation process carried out in a reactive distillation zone which includes at least one catalytic zone flanked by two distillation zones, the vapor from the distillation circulating from bottom to top so as to be in practically no contact with the catalyst, and the liquid circulating from the upper distillation zone (5) to a substantially central zone at the bottom of the catalytic zone without contacting the catalyst, then circulating radially below the catalytic zone via at least one means (20) so as to be introduced into a liquid distribution zone (23), then circulating through the catalytic bed (8) in the catalytic zone, following which the liquid is recovered via at least one liquid overflow means (19) in a lower distillation zone (14). The invention also concerns an apparatus for reactive distillation.
