The application of activated alumina in the field of adsorption is used as an adsorbent. It is one of the main uses of activated alumina. This is mainly due to its large specific surface area, reasonable pore structure, good physical properties, and good chemical stability. Favorable factors. Its important industrial applications include dry gas, dry liquid, purified water treatment, selective adsorption in the petroleum industry, etc.

1) Application of gas drying Because activated alumina and water have a strong affinity, it has a very strong ability to dry moisture in the gas. It can dry acetylene, hydrogen, oxygen, air, nitrogen, etc. More than one kind of gas.

2) Application in water purification The development of activated alumina in the field of water purification is very rapid. The treatment of water quality mainly focuses on the removal of fluoride, the removal of color and odor, and the removal of phosphate.

3) Application in liquid drying Liquid drying is much more complicated than gas drying, and the requirements for desiccant are relatively high. First, when the liquid is in contact with the adsorbent, no chemical reaction can occur between the components of the liquid and between the liquid and the oxygen adsorbent. Second, the adsorbed substances of the dry liquid can be washed away during regeneration. At present, the liquids that can be dried by alumina include co-aromatic hydrocarbons, high molecular olefins, gasoline, and kerosene.
