Brief

Activated alumina ball has a large capacity of absorption high strength and thermal stability, widely used as an absorber, desiccant and catalyst carrier in chemical, petrochemical industry etc.


Activated alumina ball Details

Activated alumina ball

Presents in white beads, uniform granularity, smooth surface, large mechanical strength, can not be dissolved in the water and organic solvent, but it can be dissolved in the strong acid and alkali solution. It has strong ability of moisture absorption, and can not swell and crack after absorbing water and keep the original shape at the same time, It is innoxious, flavorless.

Activated alumina ball Main usage
as absorbent, it is mainly used in different kinds of hydrocarbon gas, natural gas, petroleum cracking gas to absorp, Dehydrate, which belongs to the universal type. As fluorineremoval agent is mainly to remove the fluorine in the drinking water, industrial water; As recycling agent, it is used in the anthraquinone process hydrogen peroxide as absorbent. As dechlorination agent, it is mainly used for dechlorination in the different kinds of gases and viscosity resin liquid; As catalyst carrier, it is mainly used for all kinds of catalyst carrier. As air drier, it is used as drier in the air.
