Product Details


The spherical activated alumina adsorbent is a white spherical porous particle. Activated alumina is with uniform particle size, smooth surface, high mechanical strength and strong hygroscopicity. It will not swell or crack and will remain intact after absorbing water. It is non-toxic, odorless and insoluble in water and ethanol. Activated alumina is an efficient desiccant for deep drying of trace water. It is very suitable for non-thermal regeneration device.

Alumina (AL2O3) used in catalysts is commonly referred to as activated alumina. It is a porous, highly dispersed solid material with a large surface area. Its microporous surface has the characteristics required by catalysis, such as adsorption, fluoride removal and drying. Because of its properties, surface activity and excellent thermal stability, it has been widely used as home desiccant, catalyst and catalyst carrier for chemical reaction.


Activated alumina can selectively adsorb water in gases, vapors and some liquids. When the adsorption is saturated, the water can be removed and reactivated by heating at about 175-315 ~C. Adsorption and reactivation can be carried out many times. In addition to being used as a desiccant, it can also absorb the vapor of lubricating oil from contaminated oxygen, hydrogen, carbon dioxide, natural gas, etc. It can also be used as catalyst, catalyst carrier and chromatographic analysis carrier.

Activated alumina belongs to the category of chemical alumina. It is mainly used for adsorbents, water purifiers, catalysts and catalyst carriers. According to different uses, its raw materials and preparation methods are different.

【Fators that will affect the adsorption of Activated alumina balls 】
⑴ Particle size: The smaller the particle size, the higher the adsorption capacity, but the smaller the particle size, the lower the particle strength, affecting its service life.

⑵ PH value of raw water: When the PH value is greater than 5, the lower the PH value, the higher the adsorption capacity of activated alumina.

⑶ Raw water alkalinity: High bicarbonate concentration in raw water will reduce the adsorption capacity.

⑷ Chloride ion and sulfate ion.

⑸ The effect of arsenic: Activated alumina can adsorb arsenic in water. The accumulation of arsenic on activated alumina results in a decrease in the adsorption capacity of fluoride ions,

and makes it difficult to elute arsenic ions during regeneration.
