Activated alumina technical indicators

Activated alumina technical indicators

Appearance of activated alumina: activated alumina is white spherical porous particles with uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, no swelling or cracking after water absorption, non-toxic, odorless, insoluble in water and ethanol, It has strong adsorption to fluorine and is mainly used for defluorination of drinking water in high fluoride areas.

Activated alumina has selective adsorption capacity for gas, water vapor and moisture in some liquids.

After the adsorption is saturated, it can be heated at about 175-315 ° C to remove water and resurrected. Adsorption and resurrection can be performed multiple times.

In addition to being used as a desiccant, it can also absorb the vapor of lubricating oil from polluted oxygen, hydrogen, carbon dioxide, natural gas, etc.

And can be used as catalyst and catalyst carrier and chromatographic analysis carrier. Under certain operating conditions and regeneration conditions of activated alumina, the drying depth of this product is as high as the dew point temperature below -70 degrees.

Application of activated alumina

Activated alumina products can be used as defluorination agent for high fluoride drinking water (large defluorination capacity), defluorination agent for circulating alkane in alkylbenzene production, deacidification and regeneration agent for transformer oil, used in oxygen production industry, textile industry, Gas drying in the electronic industry, drying of automatic instrument air, as desiccant and purifying agent in fertilizer, petrochemical drying and other industries (dew point can reach -40 degrees), in the air separation industry, pressure swing adsorption dew point can reach -55 degrees. It is a highly efficient desiccant for deep drying of trace water. Ideal for heatless regeneration units.
