Paglalarawan
Ang aluminyo oxide na ginamit bilang desiccant, adsorbent, catalyst at catalyst carrier ay tinatawag na "activated alumina", na may porous, mataas na pagpapakalat at malaking scale na akumulasyon, at malawakang ginagamit sa mga patlang ng petrochemical, fine kemikal, biological at parmasyutiko.
Ang aktibong alumina ay karaniwang ginawa ng aluminyo hydroxide heating at dehydration. Aluminum hydroxide is also known as hydrated aluminum oxide, and its chemical composition is Al2O3· nH2O, is usually different by the number of crystalline water contained. Matapos ang aluminyo hydroxide ay pinainit at dehydrated, maaaring makuha-al2O3.

Application
Ang aktibong alumina ay kabilang sa kategorya ng kemikal na alumina, higit sa lahat na ginagamit para sa desiccant, adsorbent, ahente ng paglilinis ng tubig, katalista at carrier ng katalista. Activated alumina has the selective adsorption of gases, water vapours and certain liquids. The adsorption saturation can be revived by heating and removing the water at about 175~315 ℃. Multiple adsorption and desorption can be performed.
Bukod sa paglilingkod bilang isang desiccant, ang mga pampadulas na singaw ay maaari ring makuha mula sa kontaminadong oxygen, hydrogen, carbon dioxide, natural gas at iba pa. It can be used as catalyst and catalyst carrier and color layer analysis carrier. Maaari itong magamit bilang mataas na tubig na inuming fluorine (malaking kapasidad ng fluorine), defluoride ng nagpapalibot na alkan adsorption dew point up to-55 ℃ in air separation industry. It is a highly efficient desiccant with deep drying of trace water. Very suitable for heat-free regeneration units.
