Aluimina is used for drying of air, gases, liquids.
Purification and conditioning of insulating oil and
industrial oils. Activated Alumina is also used for
Removal of acidic impurities and trace metal scavanging
in organic streams and inorganic gases. Removal of oil
vapors from gases. Purification of drinking water e.g.
removal of floride compounds etc. Activated Alumina
can be used in refrigeration circuits, transit packing
for goods like electronic, pharmaceutical and food.
Activated Alumina as catalyst & catalyst bed support
/ carriers. Activated Alumina is also used as fire retardant
Activated Alumina are :
porous form of aluminum oxide.
of adsorbing and holding moisture withour change in
form of properitis.
inert to most of vapors and gases.
and will not swell or disintigrate when immersed in
resistant to shock and abrasion.
of producing Dew Point up to (-) 80 Deg.C. under specific
emloying temperature: With dry gas : 120 Deg. C. - 150
Deg.C. With dry gas : 200 Deg.
C. - 250 Deg.C.
up to maximum reactivation temperature of 315 Deg.C.
without any appreciable reduction
of useful life.
of being reactivated for almost unlimited number of
of Activated Alumina :
Form : Sphere (Balls).
: 2-5, 3-6, 5-8 mm
Density : 0.75 to 0.85 Gms/Liter.
Area : 345 to 415 M2/Gm.
Volume : 0.40 to 0.50 CC/Gm.
Capacity (at 60 % RH) : 21.5 %.
Loss : 0.2 %.
of Activated Alumina:
is used for drying of high pressure air feed and gases
up to Dew Point of (-) 70 Deg.C. and organic liquid to moisture
level of and below 10 ppm. The gases and liquids that can
be dried using Activated Alumina are as follows :
Gases : Acetylene, Air, Ammonia, Argon, CO2, Cl2, Cracked
Gas, Ehane, Ethylene, Freon, Furnace Gas, He, H2, HCL,
H2S, CH4, N2, O2, Propane, Propylene, SO2 etc.
Liquids : Benzene, Butadiene, Butane, Bromine Chloride, Butyl
Acetata, Cabrbon tetra chloride, Chlorobenzenes, Cyclohezane,
Ethyle, Hexane, Hydraulic Oils, HF alkylation feed, Jet Fuel,
Kerosene, Lubricating Oils, Naphthas, Nitrobenzene, Pipeline
products,Hylene, Refrigerants,Vegetables Oils, Transformer
from drying, due to its high porosity and large surface area,
Activated Aluminas are also used as CATALYSTS & CATALYST CARRIERS.
The reactions involving Aromatization, Dehy- deration, Desulfurization
, Hydrocarbon cracking , Hydrocarbon Synthesis , Hydroforming,
Oxidation, Hydrogenation and Isomerization etc.
