Activated Alumina Balls


The  Activated   Alumina   is a highly porous,   granular form   of aluminium  oxide having preferential adsorptive capacity for moisture and odor container in gases and some liquids.  When saturated, it can be regenerated by heat (176o – 325oC).  The cycle of adsorption and reactivation can be repeated many times.

GAS DRYING  Gases that can be dried by activated aluminas are Acetylene, Air, Ammonia, Argon,   Carbon dioxide,   Chlorine,   Cracked gas, Ethane,  Ethylene,  Freon,  Furnace gas, Helium,   Hydrogen,  Hydrogen Chloride, Hydrogen Sulfide, Methane, Natural gas, Nitrogen, Oxygen, Propane, Propylene, Sulphur dioxide etc.

LIQUID DRYING  Liquids   that  can be dried by activated alumina are Benzene, Butadiene, Butane,    Butyl  acetate, Carbon tetrachloride, Chlorobenzene, Cyclohexane, Ethyl acetate, Freon,   Gasolines,   Heptane,   Hexane,  Hydraulic oils, Jet fuel, kerosene, Lubricating oils, Naphtha,     Nitrobenzene,     Pentane,   Pipe   line products ,   Propane, Propylene, Styrene, Toluene, Transformer oil, Vegetable oil, Xylene, etc.

As a desiccant, activated aluminas is capable of removing significant amount of water from liquids and essentially, all water from gases. As a absorbent activated alumina can perform variety  of   services such as removing oil vapours   from compressed gases, removing acids from   lubricating   oils or  refrigerants,  removing fluorides from water etc. Polar molecules, such   as   water and alcohols are highly  adsorbed by activated aluminas, white nonpolar gases such as nitrogen and argon are at the low end of the adsorption scale.
