Sorbtech activated alumina spheres are very porous. They have a high surface area, which allows the adsorption of gases and liquids, and do not change form.
Activated alumina spheres won’t soften or disintegrate when immersed in liquids. When used to adsorb water, the activated alumina spheres act as an efficient desiccant.
Molecules with the highest polarity are preferentially adsorbed.
In the absence of irreversible fouling, the activated alumina spheres may be regenerated to their original adsorption efficiency by heating to a temperature between 350-600°F (177-316°C).
It is recommended to regenerate the alumina prior to reuse. To regenerate the alumina it is heated to a high temperature, at low pressure, with dry, inert gas.
