Abstract

La présente invention concerne un procédé de séparation d'isomères par adsorption sur lit mobile simulé (LMS), comprenant la séparation des matériaux bruts comprenant des isomères par adsorption LMS, ledit LMS comprenant de nombreux lits d'adsorption dont chacun est équipé de grilles, chacune des grilles étant équipée de la canalisation de chargement et de déchargement de la charge d'alimentation du lit, la charge d'alimentation chargée dans le LMS et déchargée de celui-ci, comprenant au moins des charges d'alimentation, un désorbant, un extrait et un raffinat, l'extrait étant enrichi en produit cible, caractérisé en ce que l'extrait est utilisé comme liquide de rinçage et respectivement chargé dans un premier ou un deuxième lit en amont de la position de chargement de charge d'alimentation et l'un des deuxième à quatrième lits en aval de la position de retrait d'extrait. Un tel procédé est utilisé pour la séparation d'isomères aromatiques en C par adsorption et peut améliorer la capacité du dispositif tout en augmentant efficacement la pureté du produit cible séparé par adsorption.
