Abstract
A high-porosity, high-surface area, low-density alumina and a method for preparing said alumina. The alumina typically has a surface area from about 260 to about 400 m.sup.2 /g, a pore volume from about 1.0 to about 2.75 cc/g, a loose bulk density from about 7.5 to about 25 lb/ft.sup.3, and is produced by contacting aqueous alumina slurries with an effective amount of an organic solvent and drying the resulting solvent-aqueous alumina mixture.
