Active alumina
Name：Active alumina
CAS：1344-28-1
Molecular Formula：Al2O3
Standard：CE or HG/T3927-2007
Activated alumina is an excellent desiccant absorbent for drying a wide variety of liquids and gases. Our activated alumina has been developed with high attrition resistance and crush strength, It has larger water adsorption capacity comparing to molecular sieve at high relative humidity and providing long service life with performance at or below dew point specifications. Activated alumina is widely used in large and small dryers. It is appropriate for use in dehydrating gases in both thermally regenerative and pressure swing adsorption (PSA) process.

Note: The above data is typical value for reference only. We can also design as per customers’ request
Main Application：
Super Drying capacity for gases including Acetylene, hydrogen, oxygen, air, nitrogen...etc
For water purification:it has fast purification capacity for water purification treatment especially for fluoride,color,and odor removal ,phosphate removal.
Drying for Liquids: it is more complicated than drying for gases, mainly drying for Aromatic hydrocarbons,Polymer alkenes,Gasoline, kerosene..etc
Used as catalyst:In many industrial catalytic processes, alumina is not only used as catalyst,or Carrier of active component of catalyst.
Packaging:
Steel drum, paper drum,aluminum foil bag or per customer’s request.
Storage:
The product as desiccant cannot be exposed in the open air and should be stored in dry condition with air-proof package.
