Abstract

UNA MEZCLA DE SUMINISTRO DE AROMATICOS C 8 NO EQUILIBRADA SE ISOMERIZA SELECTIVAMENTE PARA OBTENER UN PRODUCTO ISOMERIZADO ENRIQUECIDO EN PARA-XILENO MEDIANTE LA PUESTA EN CONTACTO DEL SUMINISTRO EN LA PRESENCIA DE HIDROGENO CON UN CATALIZADOR QUE CONTENGA UNA COMBINACION DE UN COMPONENTE DEL GRUPO DEL PLATINO CON UN TAMIZ MOLECULAR DE SILICOALUMINOFOSFATO CRISTALINO ACIDICO SM-3 EN CONDICIONES DE ISOMERIZACION DE AROMATICOS C{SUB, 8}. EL TAMIZ MOLECULAR SM-3 ESTA ENRIQUECIDO EN EL SILICIO DE LA ESTRUCTURA EN LA SUPERFICIE, RESULTANDO UN MAYOR RENDIMIENTO DE PARA-XILENO EN COMPARACION CON LOS PROCEDIMIENTOS YA CONOCIDOS.
