Abstract

ESTA INVENCION SE REFIERE A UN PROCESO EN EL CUAL UNA OLEFINA LINEAL SE CONVIERTE BAJO CONDICIONES DE ISOMERIZACION EN SU CORRESPONDIENTE ISOOLEFINA RAMIFICADA CON METILO MEDIANTE EL CONTACTO A UNA TEMPERATURA DE ENTRE 200 Y 650 GRADOS CENTIGRADOS COMO UN CATALIZADOR DE ISOMERIZACION QUE COMPRENDE (I) AL MENOS UNO ZEOLITO QUE TIENE SOLAMENTE EN UNA DIMENSION UNA ESTRUCTURA DE POROS QUE TIENE UN TAMAÑO DE PORO LO SUFICIENTEMENTE PEQUEÑO PARA RETARDAR LA DIMERIZACION DEL SUBPRODUCTO Y LA FORMACION DE COQUE Y LO SUFICIENTE MENTE GRANDE PARA PERMITIR LA ENTRADA DE LA OLEFINA LINEAL Y PARA PERMITIR LA FORMACION DE ISOOLEFINA RAMIFICADA CON METILO, (II) UN AMALGAMADOR DE ALUMINA Y (III) HASTA ALREDEDOR DEL 15% DE SU PESO DE UN METAL PROMOTOR DE LA OXIDACION DEL COQUE. DESPUES DE UN PERIODO DE FUNCIONAMIENTO, CUANDO SE HA DEPOSITADO SUFICIENTE COQUE SOBRE EL CATALIZADOR EN UNA CANTIDAD PARA REDUCIR SIGNIFICATIVAMENTE LA ACTIVIDAD DEL CATALIZADOR, EL CATALIZADOR ES DESPOSEIDO DEL HIDROCARBONO Y SEPONE EN CONTACTO ENTONCES A TEMPERATURA ELEVADA CON UN GAS QUE CONTENGA OXIGENO DURANTE UN TIEMPO SUFICIENTE PARA QUEMAR EL COQUE, POR EJEMPLO, PARA REGENERAR EL CATALIZADOR A UNA TEMPERATURA INFERIOR DE ALREDEDOR DE 565 GRADOS CENTIGRADOS. DESPUES DE LA REGENERACION, SE CONTINUA EL PROCESO DE ISOMERIZACION. EL USO DE PALADIO Y/O PLATINO COMO METAL PROMOTOR DE LA OXIDACION DEL COQUE ES PARTICULARMENTE DESEABLE.
