Abstract

PIEZAS PRENSADAS A BASE DE OXIDO ALUMINICO OBTENIDO PIROGENICAMENTE CON LAS SIGUIENTES CARACTERISTICAS FISICO- QUIMICAS: DIAMETRO EXTERIOR 2 A 15 MM; SUPERFICIE BET 60 A 115 M (AL CUADRADO) /G; VOLUMEN DE POROS 0,30 A 0,80 ML/G; RESISTENCIA A LA ROTURA 100 A 300 N; DISTRIBUCION DE POROS NINGUN PORO <5 NM DE DIAMETRO; AL MENOS 80% DELOS POROS CON UN DIAMETRO DE 10 A 40NM. COMPOSICION 94 A 99% DEL PESO DE AL2O3, RESTO SIO2. SE PRODUCEN HOMOGENEIZANDO OXIDO ALUMINICO OBTENIDO PIROGENICAMENTE CON CAOLIN Y/O GRAFITO, UREA, CERA, AZUCAR, ALMIDON, BAJO ADICION DE AGUA. A CONTINUACION SE SECA A UNA TEMPERATURA DE 80 A 120 (GRADOS) C, MACHACANDO TODO PARA FORMAR UN POLVO. ESTE POLVO SE COMPRIME PARA FORMAR LAS PIEZAS PRENSADAS Y SE TEMPLA EN UN TIEMPO DE 0,5 A 6 SEGUNDOS A UNA TEMPERATURA DE 400 A 1200 (GRADOS) C. LAS PIEZAS PRENSADAS SE PUEDEN USAR COMO PORTADORES DE CATALIZADOR Y CATALIZADOR.
