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
