Activated alumina is white spherical porous granules, smooth surface, uniform particle size, non-toxic, odorless, tasteless, insoluble in water, alcohol and organic solvents, but insoluble in acids and alkalis. 
Yuanying activated alumina has strong moisture adsorption, high mechanical strength, big specific surface area, large pore volume, high pressure-resistant, high wear-resistant, stable chemical properties, not burst after absorbing water
There are the following types of products: activated alumina desiccant, defluorination agent, activated alumina catalyst carrier, activated alumina for hydrogen peroxide, sulfur recovery catalyst, potassium permanganate ball, dechlorination agent.

Activated Alumina Defluorinating Agent
Yuanying activated alumina defluorinating agent has high defluorination capacity, and it is non-toxic, tasteless, odorless, insoluble in water and organic solvents.
Widely used for fluoride removal in high fluoride area, cyclic alkanes defluorinating agent among alkylbenzene production. This product can also be used for dearsenification, wastewater decolorizing, deodorizing, etc.
Activated alumina defluorinating agent is white spherical porous particles, uniform particle size, smooth surface, high mechanical strength, hygroscopicity strong, does not crack and inflate after absorbing water.
Fluorine is one of the trace element necessary for animal and human. Adult normal daily intake should be 2~3 mg, too much or too little can lead to disease, so defluorination is important in drinking water. Activated alumina has good strength, good abrasion resistance, long service life, stable performance, high defluorination capacity, after defluorination the water quality accords with national health standards, so activated alumina is one of the indispensable material in water treatment.
Activated alumina defluorinating agent has amphoteric adsorption properties, by regulating the PH value of aqueous solution, anions in aqueous solution can be detached. Defluorinating equipment is similar to ion exchanger, in order to obtain high defluorination capacity, need to lower PH value, while the PH value is 5.5, activated alumina adsorption rate of fluorine is the largest. In order to meet the quality requirement and control corrosion, PH values should be slightly acidic. Activated alumina defluorination is similar to the anion exchange resin, but the selectivity for fluoride ion is larger than the anion resin.
Smaller particle size can increase specific surface area, make a fully contact between activated alumina and water. For example, commonly used 1-3 mm, 0.4-1.2 mm, their specific surface area are generally more than 320 m2/g. High specific surface area means huge number of micropore, it can ensure a strong adsorption of fluoride ion in water. When raw water PH value and alkalinity is lower, defluorination capacity of activated alumina is higher, fluoride absorption of per cubic meter activated alumina is 6400 grams, fluoride absorption capacity is greater than 4.0mg/g, and the price is lower than synthetic resin.

Activated Alumina for Hydrogen Peroxide
Activated Alumina for hydrogen peroxide is white, spherical porous material and is non-toxic, odorless, tasteless. It is insoluble in water, esters, hydrocarbons, alcohols and other organic solvents. It has long life, not powdering and softening in water and alkali, is a special adsorbent for anthraquinone production of hydrogen peroxide.
Besides adsorbing alkali in the working fluid, it also has strong reproductive property to the hydrogenation breakdown products, and the increase of degradation products in the hydrogenation reaction can be converted into the active anthraquinone, which can ensure the stability of the total effective amount of anthraquinone, and is conducive to the oxidation reaction, so it can reduce the amount of anthraquinone added, saving the running cost.
Considered the regeneration, this product guarantees the good machine capability, and the active changes small after regeneration.

Activated Alumina Catalyst Carrier
Yuanying activated alumina catalyst carrier is a white, spherical porous material, non-toxic, odorless, not powdering, insoluble in water and alcohol. It has even micro-holes, appropriate aperture size, big pore volume, high water absorption, small bulk density, good mechanical properties, good stability, suitable for catalyst Carrier.
Application
(1) The Co-Mo sulfur-resistant shift catalysts produced by Activated alumina catalyst carrier has good low-temperature activity, width working temperature, short vulcanization time and other merits, it is applicable to small and medium sized ammonia factory.
(2) In the natural gas and petrochemical refining industrial process, to the hydrogen sulfide, can use activated alumina as catalyst for sulfur recovery.
(3) The most widely application for activated alumina catalyst carrier is hydrotreating, it can raise H/C ratio and get rid of O, S, N, finally can remove V, Ni and other contaminants.
(4) Another application for the activated alumina catalyst carrier is automobile exhaust catalyst, it can promote the oxidation of hydrocarbons, carbon monoxide and nitric oxide in exhaust gas, reduce air pollution.
(5) In the petroleum hydrocracking, hydrogenation refining, hydrogenation reforming, drogenation reaction and automobile exhaust purification process, activated alumina catalyst carrier plays an important role.
(6) Used for Alcohol dehydration, olefin isomerization, hydrogenation, oxidation and polymerization.
γ-Al2O3, was called activated alumina, is a kind of porous high dispersion solid materials, because of its adjustable pore structure, large specific surface area, good adsorption performance, surface with the advantages of acidity and good thermal stability, microporous surface with requisite properties of catalytic action, therefore become the most widely used catalyst, catalyst carrier and chromatography carrier in the chemical and oil industry, and plays an important role in the oil hydrocracking, hydrogenation refining, hydrogenation reforming, dehydrogenation reaction and automobile exhaust purification process.
γ-Al2O3 is widely used as catalyst carrier because of the adjustability of its pore structure and surface acidity. When γ- Al2O3 is used as a carrier, besides can have the effects to disperse and stabilize active components, also can provide acid alkali active center, synergistic reaction with the catalytic active components. The pore structure and surface properties of catalyst depend on γ-Al2O3 carrier, so high performance carrier would be found for specific catalytic reaction by controlling the properties of γ-Al2O3 carrier.
