Activated Alumina

  • Description
  • Aluminum oxide used as desiccant, adsorbent, catalyst and catalyst carrier is called "Activated alumina", which has porous, high dispersion and large scale accumulation, and is widely used in the fields of petrochemical, fine chemical, biological and pharmaceutical.
  • Activated alumina is generally made by aluminum hydroxide heating and 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. After the aluminum hydroxide is heated and dehydrated, can obtaineρ-Al2O3.
  • Application
  • Activated alumina belongs to the category of chemical alumina, mainly used for desiccant, adsorbent, water purification agent, catalyst and catalyst carrier. 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.
  • Besides serving as a desiccant, lubricant vapours can also be absorbed from contaminated oxygen, hydrogen, carbon dioxide, natural gas and so on. It can be used as catalyst and catalyst carrier and color layer analysis carrier. It can be used as high fluorine drinking water (large fluorine capacity), defluoride of circulating alkane in alkylbenzene production, deacid regenerating agent of transformer oil, gas drying in oxygen industry, textile industry, electronic industry, automatic instrument wind, drying agent in chemical fertilizer, petrochemical drying, purification agent (dew point up to-40 ℃), and variable pressure 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.
