Activated alumina contains a dense network of micro-pores, which gives it a very large specific surface area. It is therefore used as an adsorbent, a desiccant, a defluorinating agent, and a catalyst carrier. As a trace-moisture desiccant and a polar-molecule adsorbent, it attracts polar substances selectively, and the bonding force it develops toward water, oxides, acetic acid, and alkalis is strong. The beads are produced with high mechanical strength and low abrasion; they do not soften, swell, dust, or crack on contact with water, and they retain their granular structure through repeated adsorption and regeneration cycles. Activated alumina is used widely for the deep drying of cracked gas, ethylene, and propylene; in hydrogen generation and air separation units; for instrument air drying; and in fluorine control in H2O2 production. It is also applied to the adsorption of pollutants such as H2S, SO2, HF, and paraffin in water gas, and particularly for fluoride removal from drinking water.
