Alumina, Activated

Name:
Alumina, Activated
Detailed information:
A highly porous, granular form of aluminum oxide having preferential adsorptive capacity for moisture and odor contained in gases and some liquids. When saturated, it can be regenerated by heat (176–315C). The cycle of adsorption and reactivation can be repeated many times. Granules range in size from powder (7 microns for chromatographic work) to pieces approximately 1.5 inches in diameter. Average density approximately 50 lb/cu ft.

Use:

An effective desiccant for gases and vapors in the petroleum industry. It is also used as a catalyst or catalyst carrier in chromatography, and in water purification.
