Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA FABRICACION DE AGREGADOS DE ALUMINIO ACTIVO Y A LOS AGLOMERADOS OBTENIDOS SEGUN ESTE PROCEDIMIENTO. SE REFIERE, MAS PARTICULARMENTE, A UN PROCEDIMIENTO QUE CONSISTE EN FORMAR UN CUERPO DE ALUMINIO POR AGLOMERACION DE UN POLVO DE ALUMINIO OBTENIDO POR DESHIDRATACION RAPIDA DE UN HIDROXIDO DE ALUMINIO, CARACTERIZADO PORUQE CONSISTE EN: (I) REALIZAR UNA MADURACION DE ESTOS CUERPOS DE ALUMINIO EN UNA ATMOSFERA DE TASA DE HUMEDAD CONTROLADA; (II) IMPREGNAR LOS CUERPOS MADURAS CON UNA DISOLUCION DE UNO O VARIOS ACIDOS; (III) SOMETER ESTOS CUERPOS IMPREGNADOS A UN TRATAMIENTO HIDROTERMICO EN UNA ATMOSFERA CERRADA; Y (IV) SECAR Y CALCINAR ESTOS CUERPOS. EL PROCEDIMIENTO DE LA INVENCION PERMITE CONSERVAR EL REPARTO DE POROS EN EL CURSO DE LAS ETAPAS DE MADURACION Y AUTOCLAVADO. LOS AGLOMERADOS DE LA INVENCION SON ESPECIALMENTE UTILES COMO SOPORTES DE CATALIZADOR O ABSORBENTE.
