Abstract

LA INVENCION SE REFIERE A COMPOSICIONES A BASE DE OXIDO CERICO CUYA SUPERFICIE ESPECIFICA A SIDO ESTABILIZADA POR ADICION DE SILICIO. ESTAS COMPOSICIONES PRESENTAN, TRAS LA CALCINACION A 800 (GRADOS) C DURANTE 6 HORAS, UNA SUPERFICIE ESPECIFICA DE AL MENOS 40 M2/G, TRAS LA CALCINACION A 1000 (GRADOS) C DURANTE 6 HORAS, UNA SUPERFICIE ESPECIFICA DE AL MENOS 20 M2/G. SU CONTENIDO EN SILICIO ES PREFERENTEMENTE INFERIOR A 1% EN PESO. PRESENTAN UN TAMAÑO DE CRISTALITOS NOTABLEMENTE PEQUEÑO, INCLUSO A ALTAS TEMPERATURAS. SE OBTIENEN SEGUN UNO DE LOS PROCESOS QUE CONSISTE EN AUTOCLAVAR EN MEDIO BASICO Y EN PRESENCIA DE UN COMPUESTO DE SILICIO, UNA SUSPENSION DE HIDROXINITRATO DE CERIO, EN RECUPERAR EL PRODUCTO OBTENIDO, Y DESPUES EN CALCINARLO. LAS COMPOSICIONES PUEDEN SER UTILIZADAS COMO CATALIZADORES Y/O SOPORTE DE CATALIZADORES.
