Activated alumina

Activated alumina (molecular formula Al2O(3-x)(OH)2x,0 < x < 0.8) is one of the most widely used inorganic chemical products in the world.Due to its porous structure, high specific surface area and unstable transition state, activated alumina has greater activity.It is widely used as catalyst and catalyst carrier in petrochemical industry and fertilizer industry.Activated alumina has adsorption characteristics, so it is used as desiccant for gas and liquid, adsorbent for gas purification, defluorination agent for drinking water, color and odor elimination agent for industrial sewage, etc.At present, the main industrial activated alumina products are produced by rapid dehydration.Activated alumina refers to the calcined alumina which is fully finely ground and basically composed of (20%-90%) alpha-al2o3 with the original crystal size of 1 micron.Formula: Al2O3, Molecular Weight: 101.96.

Activated alumina is widely used in petrochemical, oil refining, electronics, ethylene, propylene, air and other drying devices, has been used in many hydrogen peroxide plants, fertilizer plants, oxygen plants and petrochemical refining units, and has achieved good results.Activated alumina ball also according to the polarity of adsorbent to determine the strength of water, oxide, acetic acid, alkali and other strong affinity, is a moisture depth desiccant, adsorption of polar molecules adsorbent.It can be widely used in the deep drying of petroleum cracking gas, ethylene propylene gas, hydrogen production, air separation device, instrument air drying machine, fluoride treatment in hydrogen peroxide, also can remove sulfur gas hydrogen, carbon dioxide, hydrogen fluoride, hydrocarbons and other pollutants in the waste gas, especially suitable for fluorine containing water.

Active alumina is white or small globular grain of micro red, have a lot of wool stoma and taller activity, management tall fluorine water effect is good, easy regenerating, interference content is little, besides those who use at drinking water besides fluorine action, still can use as adsorbent, desiccant and catalyst carrier.It is widely used in tap water engineering, water purification engineering, hydrogen peroxide plant, fertilizer plant, oxygen plant and petrochemical industry.Activated alumina has adsorption properties, catalytic activity of porous, high dispersion, large specific area of alumina, suitable for a variety of gas and liquid drying, can be used for drinking water and industrial equipment deoxidization, defluorination, dearsenization, sewage decolorization, deodorization and so on.This product is made of high purity alumina through scientific preparation and catalytic finishing.It is used as adsorbent, desiccant, catalyst and carrier in many reaction processes such as petroleum, chemical fertilizer and chemical industry.According to its USES can be divided into: activated alumina adsorbent, desiccant and catalyst carrier.

Activated alumina is made of high purity alumina through scientific preparation and catalytic finishing.White spherical porous particles, particle size uniform, smooth surface, mechanical strength, strong hygroscopicity, after water absorption does not expand and do not crack the original, non-toxic products, tasteless, odorless, insoluble in water and organic solvents.It is a molecular adsorbent with large specific surface area.When the PH value and alkalinity of raw water are low, the fluorine removal capacity is higher than 3.0mg/g.Can be used in drinking water and industrial equipment defluorination, dearsenic, sewage decolorization, deodorization, etc.The main products are: activated alumina fluoride remover, activated alumina desiccant, activated alumina catalyst, hydrogen peroxide special activated alumina.

Activated alumina desiccant: this product is a kind of microporous and spherical material, with strong adsorption function, large specific surface area, high compressive hardness, long service life, and can be used repeatedly by regeneration method.This product is white, spherical porous material non-toxic, odorless, non-powdery, insoluble in water.It is widely used in petrochemical industry, chemical industry, textile industry, gold industry and other industries, such as instrument wind drying, pressure swing adsorption air separation device, adsorption dew point can reach more than -41 degrees, also can be used for steel, petroleum cracking gas, ethylene, propylene in the liquid phase and gas phase deep drying.
