Abstract

La presente se refiere a la alúmina estabilizada con lantano que conservauna superficie elevada a temperatura alta, especialmente después decalcinarse a 1,200°C durante 4 horas. También se refiere a unprocedimiento para la preparación de esta alúmina estabilizada, a partirde un polvo de alúmina procedente de la deshidratación rápida de unhidróxido u oxihidróxido de aluminio, en que el polvo es rehidratado enpresencia de un compuesto de lantano, y luego se somete a un tratamientotérmico. También concierne a la utilización de esta alúmina estabilizadacomo soporte de catalizador.
