    1. Fluoride Removing Activated AluminaFluoride removing activated alumina is mainly used for fluoride removal from drinking water. Despite of worldwide programs for drinking water fluoridating, enough fluorine in water may result in fluorosis in Jaipur region of India or other certain regions.
    1. Hydrogen Peroxide Activated AluminaHydrogen peroxide activated alumina is mainly used for reclaiming degradation product in the working fluid on production process of hydrogen peroxide by Anthraquinone method. It is superior to other method for degradation especially used in the plants of palladium catalyst and nickel catalyst with three components.
    1. Compressed Air Drying Activated AluminaCompressed air drying activated alumina is white spherical with many capillary channels. With high activity on surface of these capillary channels, our product can express instinct of selective water adsorption from gas, steam and liquid, which provides extremely good effect of fluorine ion removal from water.
    1. Activated Alumina Catalyst CarrierThere are a variety of different activated alumina catalysts in different industries, including gamma activated product, catalyst carriers, claus catalyst and chloride removal catalyst, COS catalyst and sulfur removal catalyst, and more.
    1. Other AdsorbentsPorous materials are widely used in various industrial areas, and molecular sieve as a microporous material are popularly applied petrochemical, fine chemicals and household chemicals industries, functioning as catalysts, iron exchanges and adsorption separation materials.

Activated Alumina

Activated alumina features numerous microporous channels and large specific surface area for the use of adsorbent, desiccant, catalyst and so on. With strong affinity to water, oxide, acetic acid, alkali and more, our product is not only micro water depth of desiccant, but also an adsorbent which adsorbs polar molecules.

Product Classification

Category Application
Special use in fluoride removal and purification, as well as air drying Activated alumina can be applied to fluoride removal agent with high fluorine of drinking water or looping alkane for benzene production, and transformer oil regenerant for deacidification. As desiccant and purifying agent of industrial gas, it is widely used in petrochemical, oxygen production, textile, electronics, fertilizer and other industries.
Only used in hydrogen peroxide Due to its degradation and regeneration capacity of anthraquinone derivatives, our product is a special adsorbent for the production of hydrogen peroxide by anthraquinone method.
Catalyst carrier dedicated With good stability, it is suitable for catalyst carrier.
Catalyst for sulfur recovery Besides, activated alumina can be used as catalyst for Claus sulfur recovery unit in oil refinery of H2S acid gas, desulphurization plant for natural gas purification, city gasworks, petrochemical plant, chemical industry and so on.

HADalum® Activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material, which can have a surface area significantly over 200 square metres per gram. The compound is used as a desiccant which is to keep things dry by absorbing water from the air, and as a filter of fluoride, arsenic and selenium in drinking water. It is made of aluminium oxide, also named alumina or Al2O3, the same chemical substance as sapphire and rubies, but without the impurities that give those gems their color. It 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.

HADsiev Engineering is a specialized activated alumina manufacturer and supplier based in China. Our company also provides Compressed air drying activated alumina, 10X molecular sieve, 4A-DG molecular sieve, and more.

Other Products
    1. 3A Normal Molecular Sieve3A normal molecular sieve can be used to dry petroleum pyrolysis gas and unsaturated hydrocarbon materials, such as ethylene, propylene, butadiene, acetylene and more, or benzene, toluene, xylene and other solvents, such as methanol and ethanol. Also, it helps dry carbon dioxide gas in food grade, coal oil and jet fuel.
    1. 3A-XH Molecular Sieve Desiccant for Refrigerants3A-XH molecular sieve desiccant for refrigerants is silica aluminates in potassium and sodium form with a pore opening of 3 angstroms or 0.3 nm. It is a generic kind of desiccant, which can be classified as three types of molsieve adsorbent, XH-7 type, XH-9 type and XH-11 type.
