Abstract
METODO DE PREPARACION DE UN SOPORTE MONOLITICO MEJORADO PARA CATALIZADORES EN EL QUE SE MEZCLAN POLVOS DE ALUMINA FORMADA A PARTIR DE ALUMINA HIDRATADA Y SILICE FORMADA A PARTIR DE ALUMINA HIDRATADA Y SILICE FORMADA A PARTIR DE SILICE AMORFA, EN UNA PROPORCION DE 50 A 93% EN PESO DE ALUMINA Y DE 7 A 50% EN PESO DE SILICE. SE COMBINAN CON UN MATERIAL CERAMICO PREFORMADO, COMO FASE ESTRUCTURAL; Y SE SINTERIZAN PARA PROPORCIONAR UNA FASE DE SOPORTE DE GRAN SUPERFICIE ESPECIFICA DE UN OXIDO POROSO INTEGRADA A LA FASE CERAMICA ESTRUCTURAL SINTERIZADA. LA MAYOR EFICACIA DE LA ACTIVIDAD CATALITICA DE ESTAS ESTRUCTURAS DE SOPORTE DEL CATALIZADOR COMO CONVERTIDORES CATALITICOS EN AUTOMOVILES PUEDE MEJORAR EL RENDIMIENTO DEL COMBUSTIBLE.
