Abstract

Cette invention concerne une méthode de préparation d'une alumine contenant du trihydrate de beta alumine. Selon la présente invention, le monohydrate d'alpha alumine très pur contenant du titane et substantiellement sans ion de métal alkali est calciné à une température variant de 425 à 482 degrés C pendant une à trois heures, l'alumine calcinée résultante contenant de la gamma alumine est mélangée avec de l'eau et l'alumine imbibée d'eau qui en dérive est chauffée à un pH variant de 6 à 12,5, et à une température de 87 à 121 degrés C pendant 8 à 24 heures. L'alumine produite selon ce procédé est utilisée comme support catalytique.
