PXZT activated alumina:Primary surply of CNPC and CPPC ISO9001:2000

 Activated alumina  

Features & Application area:

large capacity of absorption, high surface area, high strength and thermal stability, which is widely used as an absorbent, desiccant and catalyst carrier in chemical, petrochemical and fertilizer industries. 

Classification:

KA401 activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in 

a way that produces a highly porous material; this material can have a surface area significantly

over 200 m2/g. 

KA402 activated alumina is also widely used to remove fluoride from drinking water.  Basically, 

the more alumina in the filter, the less fluoride will be in the final, filtered water. Lower temperature water,

lower pH water (acidic water) are filtered more effectively.

KA403 is for absorbent H2O2

KA404 is for chlorine absorbent

KA405 activated alumina is used for a wide range of adsorbent and catalyst applications including 

the adsorption of catalysts in polyethylene production, in hydrogen peroxide production, as a selective

adsorbent for many chemicals including,in  removal from gas streams .

KA406 activated alumina is used as a charge material in foreline traps to prevent  generated by  from 

backstreaming into the system
