Abstract

LA INVENCION SE REFIERE A UN PROCESO MULTIETAPA PARA PRODUCIR POLIETILENO QUE TENGA UNA DISTRIBUCION DE PESO MOLECULAR BIMODAL Y / O ESTRECHA EN LA PRESENCIA DE UN SISTEMA CATALIZADOR DE POLIMERIZACION DEL ETILENO EN UNA SECUENCIA DE REACCION MULTIETAPA, EN LA CUAL EL PRIMER PASO DE REACCION ES UN PASO DE POLIMERIZACION DE LA FASE LIQUIDA Y EL SEGUNDO PASO DE REACCION ESTA FORMADO POR UNO O MAS PASOS DE POLIMERIZACION DE FASE GASEOSA. DE ACUERDO CON EL PROCESO DE LA INVENCION EN EL PRIMER PASO DE LA REACCION EL ETILENO SE POLIMERIZA EN UN REACTOR DE BUCLE (10) EN UN MEDIO DE HIDROCARBONO INERTE DE BAJA EBULLICION, EL TIEMPO DE RESIDENCIA SERA DE AL MENOS 10 MINUTOS, LA MEZCLA DE REACCION SE DESCARGA DEL REACTOR DE BUCLE (10) Y AL MENOS UNA PARTE SUBSTANCIAL DE LA MEZCLA DE HIDROCARBONO INERTE SE SEPARA Y EL POLIMERO SE TRANSFIERE AL INTERIOR DE UNO O MAS REACTORES DE FASE GASEOSA (30), DONDE SE COMPLETA LA POLIMERIZACION EN LA PRESENCIA DE ETILENO Y OPCIONALMENTE DE HIDROGENO Y UN COMONOMERO. COMO MEDIO DE HIDROCARBONO INERTE EN EL REACTOR DE BUCLE (10) PUEDE USARSE EL PROPANO Y LA POLIMERIZACION PUEDE LLEVARSE A CABO TAMBIEN DE FORMA QUE LA MEZCLA DEL HIDROCARBONO INERTE, EL MONOMERO, EL HIDROGENO Y EL COMONOMERO OPCIONAL SE ENCUENTRE BAJO CONDICIONES SUPERCRITICAS.
