The use of activated alumina balls
The use of activated alumina balls
Activated alumina balls can absorb lubricating oil and other oil vapors from contaminated oxygen, hydrogen and sulfur dioxide, and can be used as catalysts or carriers. It is widely used in petrochemical, oil refining, electronics, ethylene, propylene, air and other drying devices, and has been used in many hydrogen peroxide plants, fertilizer plants, oxygen plants and petrochemical refining units across the country, and has achieved good results.
Activated alumina ceramic balls are also determined according to the polarity of the adsorbed material, and have strong affinity for water, oxides, acetic acid, alkali, etc. agent.
Activated alumina ceramic ball defluorination is similar to anion exchange resin, but the selectivity of fluoride ions is greater than that of anion resin, activated alumina adsorption and defluorination effect is good, and the capacity is stable. Activated alumina absorbs 6400 grams of fluorine per cubic meter. It has high strength, low wear, no softening, no swelling, no pulverization, and no cracking in water. Fluoride treatment in hydrogen peroxide, and can also remove sulfur gas hydrogen, carbon dioxide, hydrogen fluoride, hydrocarbons in waste gas. It is especially suitable for the defluorination treatment of fluorine-containing water.
