Abstract
Alumina having a pore vol. of 1.0-2.75 cm3/g., a specific surface area of 260-400 m2/g., and a heaping wt. of 0.12-0.40 g/cm3 is produced by mixing an aq. alumina slurry contg. =32 wt. % Al2O3 (pref. produced by hydrolysis of an Al alcoholate) with ethanol, propanol or butanol in an amt. at least suff. to form an azeotropic mixture with the present in the slurry, and drying the mixture. The product is suitable for catalytic applications; the pore dia. is 10000 angstroms. The product can be shaped by extrusion.
