The use of alumina in the catalyst is usually called "activated alumina",it is a porous,highly dispersed solid material,has a large surface area,its microporous surface has the characteristics required for catalysis,such as adsorption performance, surface activity,excellent thermal stability.so it is widely used as a catalyst and catalyst carrier for chemical reactions.
Application
Activated alumina has a wide range of applications,mainly including adsorbent, desiccant, catalyst and catalyst carrier.the main industrial applications of activated alumina as an adsorbent include gas drying,liquid drying,water purification,selective adsorption in the petroleum industry and chromatographic separation processes.

Detailed Photos
Activated alumina has uniform particle size,smooth surface,high mechanical strength,strong hygroscopicity,does not expand or crack after water absorption,non-toxic,odorless,insoluble in water and ethanol.activated alumina is a kind of highly efficient desiccant for deep drying with trace water,which is suitable for non-heat regeneration equipment.
In addition to being used as a desiccant,it can also adsorb the vapor of lubricating oil from polluted oxygen,hydrogen,carbon dioxide, etc.it can be used as catalyst,catalyst carrier and chromatographic analysis carrier.
