Learn about activated alumina ball in one minute

Jun. 12, 2020

Activated alumina ball, also known as modern water purification activated bauxite, is a kind of porous, high dispersibility solid material. It has a large surface area. Its microporous surface has the characteristics of adsorption, defluorination, drying, surface activity and good thermal stability required by catalysis, so it is widely used as catalyst and catalyst carrier for household desiccant and chemical reaction.


Activated alumina ball is a kind of white spherical porous particle with uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, no expansion and cracking after absorbing water, no peculiar smell, insoluble in water and ethanol, has a strong adsorption effect on fluorine, mainly used to remove fluorine in drinking water in high fluorine area.


Activated alumina ball has the ability of selective adsorption to gas, water vapor and some liquid water. After adsorption and saturation, the water can be removed by heating at about 175-315℃, and the regeneration can be resumed. Adsorption and regeneration can take place multiple times. In addition to being used as a desiccant, it can also absorb the lubricating oil vapor in polluted oxygen, hydrogen, carbon dioxide and natural gas, and be used as a catalyst, catalyst carrier and chromatographic analysis carrier.


USES: widely used as catalyst and catalyst carrier in petrochemical industry and chemical fertilizer industry. Activated alumina ball has adsorption characteristics, can be used as gas and liquid desiccant, gas purification adsorbent, drinking water defluoridation agent, industrial wastewater color deodorant.
