Abstract

PROCEDIMIENTO MEJORADO PARA LA TRANSALQUILACION DE POLIALQUINBENCENO. CONSISTE LA INVENCION EN UN PROCESO MEJORADO PARA LA TRANSALQUILACION DE POLIALQUILBENCENOS A MONOALQUILBENCENOS EN UN REACTOR EN PRESENCIA DE UN CATALIZADOR. LA MEJORA COMPRENDE TRANSALQUILAR UNA ALIMENTACION O CARGA QUE COMPRENDA POLIALQUILBENCENOS, DE PREFERENCIA BENCENO Y POLIALQUILBENCENOS, EN UN REACTOR DE TRANSALQUILACION EN PRESENCIA DE HIDROGENO. CON ESTE PROCESO SE AUMENTA LA DURACION DE CATALIZADOR Y ES POSIBLE UTILIZAR UNA ALIMENTACION AL REACTOR DE TRANSALQUILACION QUE TENGA UNA RELACION MAS BAJA ENTRE EL BENCENO Y LOS GRUPOS ALQUILO.
