Appearance:

Activated Alumina Appearance: Activated alumina is a white, spherical, porous granule with uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, and maintains its original shape without swelling or cracking after absorbing moisture. It is odorless, insoluble in water and ethanol, and has strong adsorption for fluorine, mainly used for removing fluorine from drinking water in high-fluoride areas.

Function:

Active alumina has the ability to selectively adsorb moisture from gases, steam, and certain liquids. After adsorption is saturated, it can be heated to around 175-315℃ to remove water. Adsorption can be carried out multiple times. In addition to being used as a desiccant, it can also adsorb vapor of lubricating oil from contaminated oxygen, hydrogen, carbon dioxide, natural gas, and others. It can also be used as a catalyst and catalyst carrier, as well as a chromatography carrier.

Active Alumina falls under the category of chemical alumina and is primarily used as an adsorbent, water treatment agent, catalyst, and catalyst carrier. Depending on the specific application, the raw materials and manufacturing processes vary.

Active alumina, under certain operating conditions, achieves a dryness below -70 degrees Celsius of the dew point temperature.

Activated Alumina Applications: This product can be used as a defluorination agent for high-fluoride drinking water (with large defluorination capacity), a defluorination agent for cyclic alkanes in alkylbenzene production, an acid-regeneration agent for transformer oil, and as a drying agent for oxygen production, textile industry, electronics industry gas drying, automated instrument air drying, and as a drying agent and purifying agent in industries such as fertilizer and petrochemicals, where the dew point can reach -40 degrees. It is also used in air separation industry where the dew point can reach -55 degrees. It is a drying agent for trace water drying and is highly suitable for heat-free installations.
