Abstract

PROCESO DE ALQUILACION/TRANSALQUILACION QUE IMPLICA LA ALQUILACION EN FASE GASEOSA DE UNA CARGA DE BENCENO EN UNA ZONA DE ALQUILACION MULTIFASICA QUE PRESENTA MULTIPLES LECHOS CATALIZADORES CONECTADOS EN SERIE QUE CONTIENEN UN CATALIZADOR PARA LA ALQUILACION AROMATICA DE TIPO PENTASILICO COMO SILICALITA, JUNTO CON ETAPAS INTERMEDIAS DE SEPARACION Y RECIRCULACION Y TRANSALQUILACION EN FASE LIQUIDA SOBRE UN CATALIZADOR DE TRANSALQUILACION QUE COMPRENDE UN TAMIZ MOLECULAR QUE PRESENTA UN TAMAÑO DE PORO MAYOR QUE EL DE LA SILICALITA. LA CARGA QUE CONTIENE EL BENCENO SE INTRODUCE EN LA ZONA DE LA REACCION DE ALQUILACION MULTIFASICA JUNTO CON UN AGENTE ALQUILANTE C SUB,2} C SUB,4} EN CONDICIONES DE TEMPERATURA Y PRESION QUE MANTENGAN EL BENCENO EN LA FASE GASEOSA. SE RECUPERA EL PRODUCTO ALQUILADO DE LA ZONA DE ALQUILACION Y SE INTRODUCE EN UNA ZONA DE RECUPERACION DEL BENCENO, DONDE ESTE SE SEPARA DEL PRODUCTO DE ALQUILACION. EL BENCENO PROCEDENTE DE SU CORRESPONDIENTE ZONA DE RECUPERACION SE RECICLA HACIA LA ZONA DE REACCION. UNA FRACCION SEDIMENTARIA DE MAYOR PUNTO DE EBULLICION Y QUE CONTIENE UNA MEZCLA DE COMPONENTES AROMATICOS MONOALQUILADOS Y POLIALQUILADOS SE SUMINISTRA A UNA ZONA DE SEPARACION SECUNDARIA DE LA CUAL SE RECUPERA, POR LA PARTE SUPERIOR, UN COMPONENTE AROMATICO MONOALQUILADO, P. EJ., EL ETILBENCENO, Y, COMO FRACCION DE SEDIMENTO, UN COMPUESTO AROMATICO POLIALQUILADO DE MAYOR PESO MOLECULAR. ES POSIBLE APLICAR LA FRACCION DEL SEDIMENTO A UNA ZONA DE SEPARACION TERCIARIA.
