FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. Granulated active aluminium oxide has specific surface area of 180–400 m2/g, strength of 2.0–12.6 MPa, bulk density of 0.6–0.83 g/cm3, moisture capacity 0.50–0.66 g/cm3. Granular active aluminium oxide is moulded in the form of spherical granules with diameter of 2.5–10.5 mm, or in the form of cuttings with diameter of 2.5–10.5 mm, or in form of rings with outer diameter of 4–10 mm.
EFFECT: invention enables to optimize the texture of granular active aluminium oxide for making different products - catalysts, catalyst supports, dehydrators and sorbents.
