Activated alumina introduction
Activated Alumina Properties
Application: It
is mainly used in gaseous and liquid desiccation in petrochemical industry. It is also widely applied as a dryer in textile industry, oxygen making industry and automatic instrument, equipments with non-heat regeneration
Activated alumina is made of aluminium oxide (alumina; Al2O3), the same chemical substance as sapphire and rubies (but without the impurities that give those gems their color). It 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.

Characteristics of the product
Activated alumina has a very high surface-area-to-weight ratio. That means it has a lot of very small pores, almost like tunnels, that run throughout it. It has large capacity of absorption, high surface area, high mechanical strength and thermal stability.
Activated alumina is used widely in chemical, petrochemical and fertilizer industries as desiccant, absorbent, catalyst carrier, and as a filter of fluoride, arsenic and selenium in drinking water.
