Activated alumina defluoridation

Activated alumina :
large capacity of adsorption
complete in specification



Characteristics of the product
Activated alumina
is a white ball porous particle, particle size uniform, smooth surface, high mechanical strength, bibulous absorbent, after bulge not crack, non-toxic, keep the original odourless, insoluble in water, ethanol, fluorine strong adsorption, mainly used for drinking water from non-beryl area of fluoride.

Performance of the product
In certain operating conditions and regeneration conditions, the products of high temperature drying depth below 70 degrees - dew point, this product can be used from non-beryl water fluoride agent (except capacity), alkyl benzene production cycle of fluorine, alkanes of transformer oil, acid regeneration for oxygen industry, textile industry, electronic industry, industrial automation instrument wind dry gas in the dry and fertilizer, oil and chemical industry etc for dry desiccant, purifying agent (dew point can reach - 40 ° c), in air separation industry by pressure swing adsorption dew point can reach - 55 degrees. Is a trace water depth of efficient desiccant dry. It is suitable to have no hot regeneration device.
