Abstract
PROCEDIMIENTO PARA LA PRODUCCION DE UN CATALIZADOR APROPIADO PARA LA POLIMERIZACION DE OLEFINAS. SE SECA UN HIDROGEL QUE CONTIENE SILICE QUE TIENE UN PH DE 3,5 O MENOS, PARA OBTENER UN XEROGEL CON IMPORTANTE VOLUMEN DE POROS. ANTES, DURANTE O DESPUES DE LA OPERACION DE SECADO, SE UTILIZA UNA FUENTE DE CROMO PARA OBTENER UN GEL CONTENIENDO CROMO. EL SECADO SE PRODUCE DE UNA FORMA LENTA, MANTENIENDOSE A UNA TEMPERATURA INCLUIDA ENTRE 90 Y 110<025>C, A LA PRESION ATMOSFERICA, HASTA QUE SE HAYA EVAPORADO ESENCIALMENTE LA TOTALIDAD DEL AGUA. A CONTINUACION LA TEMPERATURA SE ELEVA A LA TEMPERATURA DE CALCINACION UTILIZADA PARA LA ACTIVACION DE 500<025>C. LOS TIEMPOS DE SECADO PUEDEN VARIAS ENTRE 5 Y 20 HORAS.
