Abstract

UTILIZANDO UN CATALIZADOR QUE CONTIENE UNA ZEOLITA TIPO ACIDA Y POR LO MENOS UN COMPONENTE DE METAL ELEGIDO DEL GRUPO QUE CONSTA DE RENIO, NIQUEL Y PLATA, E ISOMERIZANDO UNA MEZCLA DE LOS ISOMEROS DE DICLOROTOLUENO EN PRESENCIA DE HIDROGENO, SE PUEDE AUMENTAR LA CONCENTRACION DE POR LO MENOS UNO O MAS COMPONENTES DE LOS ISOMEROS DE DICLOROTOLUENO. SEGUN ESTE METODO SE PROPORCIONA UN PROCEDIMIENTO PARA LA ISOMERIZACION DE DCT, QUE MUESTRA UNA ALTA CAPACIDAD DE ISOMERIZACION, CAPACIDAD QUE NO SE DISMINUYE CON EL TIEMPO DE REACCION.
