    摘要: The invention concerns a process for the decomposition of tertiary alkyl ether(s), preferably selected from the group formed by ETBE, MTBE, TAME and ETAE, for the production of generally high purity tertiary olefin(s), preferably isobutene and isoamylenes, using a catalyst comprising at least one inorganic solid, for example a polysiloxane type solid, grafted with at least one alkyl sulphonic acid, aryl sulphonic acid or alkylaryl sulphonic acid type organic group.

    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.
