Abstract
PROCEDIMIENTO PARA PRODUCIR UN CATALIZADOR CONTENIENDO CROMO UTILIZADO PARA LA POLIMERIZACION EN SUSPENSION DE OLEFINAS, SE AÑADE UN SILICATO DE METAL ALCALINO A UN ACIDO PARA PRODUCIR UN HIDROGEL DE SILICE. SE LAVA PARA ELIMINAR LOS IONES DE METAL ALCALINO,SE IMPREGNA CON UNA SOLUCION ACUOSA DE UN COMPUESTO DE CROMO, COMO ACETATO DE CROMO, Y SE SECA, POR EJEMPLO, POR PULVERIZACION, PARA PRODUCIR UN XEROGEL. SE IMPREGNA ESTE CON UNA SOLUCION ACUOSA DE UN COMPUESTO DE TITANIO RESISTENTE A LA HIDROLISIS,COMO UN QUELATO DE TITANIO. EL XEROGEL IMPREGNADO SE PUEDE ACTIVAR MEDIANTE CALCINACION WN AIRE A UNA TEMPERATURA ENTRE 400 Y U.110 C. EL CATALIZADOR ACTIVADO CONTIENE DE 3 A 7 POR 100 EN PESO DE TITANIO Y DE 0,1 A 5 POR 100 EN PESO DE CROMO. EN OTRA REALIZACION SE SECA UN HIDROGEL DE SILICE QUE CONTIENE UN COMPUESTO DE TITANIO RESISTENTE A LA HIDROLISIS Y UN AGENTE DE PRESERVACION DE LOS POROS.
