Abstract

PROCEDIMIENTO PARA LA SEPARACION DE LOS DICLOROTOLUENOS ISOMEROS POR ADSORCION SOBRE ZEOLITAS DEL TIPO ZSM5. CONSISTE EN HACER PASAR UNA MEZCLA QUE CONTIENE DICLOROTOLUENOS ISOMEROS SOBRE LA ZEOLITA, SEPARANDOSE LOS DICLOROTOLUENOS NO ADSORBIDOS. SE PONE EN CONTACTO LA ZEOLITA QUE CONTIENE LOS ISOMEROS ADSORBIDOS CON EL ELUYENTE, SEPARANDOSE LOS ISOMEROS DE ESTE. LA OPERACION PUEDE LLEVARSE A CABO EN FASE LIQUIDA O EN FASE VAPOR Y ENTRE 25 Y 350JC Y EN VARIADAS PRESIONES. LA PUESTA EN CONTACTO CON LA ZEOLITA SE EFECTUA EN DISPOSITIVOS QUE PERMITAN OPERACIONES EN CONTINUO.
