Abstract

SE DESCRIBE UN PROCESO PARA LA ELABORACION CATALITICA DE CARBONATO PROPILENGLICOL (PGC) MEDIANTE TRANSFORMACION DE OXIDO DE PROPILENO (POX) Y CO2 EN PGC COMO MEDIO DE REACCION EN TEMPERATURA ELEVADA Y PRESION ELEVADA, CON SEPARACION DEL PGC FORMADO DEL CATALIZADOR. EL PROCESO SE REALIZA DE FORMA CONTINUA MEDIANTE GUIA DE TEMPERATURA ADIABATICA. POR CADA UNIDAD DE TIEMPO SE DESARROLLA EL PGC COMO MEDIO DE REACCION EN EL REACTOR EN UNA RELACION DESDE 7 HASTA 350 VECES LA CANTIDAD DE PGC FORMADO POR UNIDAD DE TIEMPO. EN TODOS LOS LUGARES DEL REACTOR SE MANTIENE EL SOBRANTE CO2 SOBRE LOS OTROS PARTICIPANTES POX. A PARTIR DE LA MEZCLA DE REACCION DE DESARROLLO SE REALIZAN DESDE 80 HASTA 98 % EN PESO EN LA ENTRADA DEL REACTOR, MIENTRAS SE ELABORA SOBRE LA BASE PGC. PARA LA ELABORACION PUEDE SER UTILIZADA LA GUIA DE TEMPERATURA ADIABATICA DEL CALOR GENERADO DEL PRODUCTO DE REACCION.
