Activated Alumina

We are engaged in the processing of quality-Activated Alumina balls, an aluminum oxide is resistant to thermal shock and abrasion. Highly porous, with tremendous surface area this alumina ball does not swell, soften shrink nor disintegrate when immersed in water.

Material Confirms specification of our Grade A: 101 for desiccant applications when tested as per IS: 9700:1991

Size Tolerance: Undersize/Oversize: Less than 5%.


Possessing higher capacity for water as compared to silica gel at elevated temperatures, it acts as desiccant for warm gases including air. Having surface area in the range 345-415 m2/gm these find wide application in :

  • Drying of organic liquids such as LPG, propylene, butene, steam cracked liquids, cyclohexane, gasoline, chloro- and fluorohydrocarbons, aromatic solvents

  • Drying of air and gases such as steam cracked gases, catalytic reforming recycle gas, synthesis gas, natural gas, CO2

  • Drying of organic liquids as LPG, aromatics, steam cracked liquids, gasoline, chloro- and fluorocarbons

  • Drying of air and gases as steam cracked gases, catalytic reforming recycle gases, synthesis gases, methyl chloride, natural gas, LNG, etc.

  • Drying of hydrogen, oxygen, nitrogen, CO2, etc

  • Purification of gases and liquids (removal of metallic traces, TBC and HF compounds) • Purification of gases and liquids (removal of metallic traces, BF3, TBC, HCl, HF and fluorinated hydrocarbons)
