ABSTRACT OF THE DISCLOSURE Granular active alumina with high mechanical durability is made by activation of an aluminium hydroxide with an apparent density in the green granular condition of at least 2.20g/cm3. The green aluminium hydroxide is subjected to compacting by dry compression before activation by a usual heat treatment. Compacting is preferably by running between two rollers. The active alumina with its high mechanical durability is well suited for a number of industrial uses such as the cleaning and drying of liquids and gases as well as catalysis.
