Activated alumina has adsorption properties, catalytic activity of porous, high dispersion, large specific surface area of alumina. It is suitable for drying a variety of gases and liquids, and is used as an adsorbent, desiccant, catalyst and carrier in many reaction processes such as petroleum, fertilizer, and chemical industry. The product is a high degree of alumina by scientific deployment, catalytic finishing. High compressive hardness, long service life, and can be used repeatedly through the regeneration method. This product is a white spherical porous material, tasteless, non-chalking, insoluble in water. It can adsorb and remove harmful fluorine in water, and can be used for fluoride removal, arsenic removal, sewage decolorization and deodorization of drinking water and industrial equipment. In the amorphous refractory ingredients can bring the following benefits: improve the density of the body, liquidity, strength, improve the amount of secondary mullite, etc., reduce the amount of water and porosity.

In addition, activated alumina can also be used as a desiccant, with large water absorption, fast drying speed, and regeneration (400 -500K baking).

Activated alumina refers to calcined alumina that has been fully finely ground and has the basic composition (20%-90%) of α- Al2O3 with the original crystal size of 1 μm.

Main uses of activated alumina: activated alumina belongs to special alumina, and its added value is much higher than that of ordinary metallurgical alumina. Activated alumina is mainly used as catalyst and catalyst carrier in petroleum, chemical industry, medicine, fertilizer and other fields. According to the pore size of alumina, it can be roughly divided into the following three categories: small pore alumina, medium pore alumina and large pore alumina. For a specific catalytic reaction, the pore size of the alumina is required to be appropriate. In addition to the pore size, the specific surface and pore volume of alumina are also basic physical parameters. Most of them require as large a specific surface and pore volume as possible, as well as alumina with concentrated pore distribution. At present, the price of boehmite in domestic and foreign markets ranges from less than 10,000 yuan to about 30000 yuan, and the price of preparing special activated alumina is higher.

After years of development, Beijing Kaibiyuan Co., Ltd. mainly produces and operates activated alumina series, activated carbon series, polyacrylamide PAM, polyaluminum chloride PAC, molecular sieve and other environmentally friendly water treatment materials. It has been widely used in electric power, petroleum, chemical, metallurgy, environmental protection, pharmaceutical, and other industries all over the country, and exported to overseas. Excellent quality, stable performance, trusted by users.

Activated alumina has many capillary channels and large surface area, which can be used as adsorbent, desiccant and catalyst. At the same time, it is also determined according to the strength of the adsorption material, which has a strong affinity for water, oxide, acetic acid, alkali, etc. It is a kind of micro-water depth desiccant and an adsorbent for adsorption molecules. Activated alumina defluoridation is similar to anion exchange resin, but anion resin selectivity for fluoride ion is large.

Activated alumina adsorption fluoride good, stable capacity, 6400 grams per cubic meter of activated alumina fluoride. This product has high strength, low wear, water immersion unchanged soft, no expansion, no powder, no rupture.

Activated alumina can be widely used in the deep drying of petroleum cracking gas, ethylene propylene gas and hydrogen production, air separation device, instrument air dryer drying, fluoride treatment in hydrogen peroxide can also remove sulfur hydrogen, sulfur dioxide, hydrogen fluoride, hydrocarbons and other pollutants in waste gas, especially suitable for fluorine-containing water defluoridation treatment.

Activated alumina generally refers to Al2O3, usually by the corresponding hydrated alumina-pseudo-boehmite (Pseudoboehmite) under high temperature heating dehydration. Due to the particularity of the catalytic industry, commercial activated alumina is generally hydrate pseudo-boehmite. Studies have confirmed that the structural properties of pseudo-boehmite determine the performance and use of the final product. Pseudo-boehmite produced by different routes and methods has different water content, which gives the product a wide range of properties.

Main raw materials and sources of activated alumina: The raw materials that can be used in this technical process include: various cheap aluminum salts, sodium aluminate, carbon dioxide and inorganic acids. The source of raw materials is wide, and low-cost waste resources such as coal gangue can be used as starting materials to obtain sodium aluminate and aluminum salt by alkali or acid dissolution.
