Abstract

L'invention porte sur un procédé d'isomérisation dans lequel l'effluent d'isomérisation (108) est fractionné dans un désisohexaniseur (116) pour donner un distillat de tête (118) contenant des diméthylbutanes, et une fraction à point d'ébullition supérieur (122), contenant de l'hexane normal, laquelle est mise en contact avec une membrane (124) à perméabilité sélective de manière à obtenir un rétentat contenant du méthylcyclopentane (128). Si on le désire, on peut recycler le perméat contenant l'hexane normal en vue de son isomérisation. Les membranes préférées sont des membranes tamis présentant un indice d'écoulement de perméat C6 d'au moins 0,01, et un rapport d'écoulement de perméat C6 d'au moins 1,25:1.
