Activated alumina can be widely used in petroleum cracking, depth ethylene propylene gas drying and hydrogen, dry air separation plant, instrument air-dry machines, hydrogen peroxide, fluoride treatment can also remove sulfur in the exhaust gas of hydrogen, sulfur dioxide, hydrogen fluoride, hydrocarbons and other pollutants, particularly adapted to fluoridated water the fluoride treatment.
High-performance activated alumina ball in monolithic refractories ingredients can bring the following benefits: Increased body density, mobility, strength, improve secondary mullite Dan Shengcheng amount, reduce the amount of water and porosity.

Decontamination mechanism activated alumina

Activated alumina is a porous, high dispersion of solid materials, a large specific surface area and pore surface has strong adsorption and moisture absorption. Mechanism of decontamination more recently on activated alumina. but there are different views. To sum up, activated alumina price to remove impurities in the water (fluorine, for example) may be two ways: One is that activated alumina fluoride removal is the adsorption process; the other is that the activated alumina defluoridation is an ion exchange process. That metal in solution electrolysis of metal ions formed by ion exchange between a series of metal hydroxides and metal oxide hydrate polyhydroxy hydrated fluoride and aluminum oxide in water surface hydroxyl functional groups., Which to achieve the purpose of removal

Application of activated alumina in water treatment

activated alumina water treatment used in the field of water treatment, mainly using its adsorption properties. Removal of contaminants, color and malodor. For example, removal of fluorine, arsenic and phosphorus, decolorization of dye wastewater treatment, papermaking wastewater deodorant alumina in water treatment is the most widely fluoride removal alumina is an amphoteric substance, isoelectric point of about pH = 9.5, when the pH <9.5, alumina adsorption anion pH> 9.5, the alumina adsorption cation

Water honeycomb activated carbon for use

Air pollution control device has two parallel adsorption composition can be used to process a batch exhaust, it is available for continuous exhaust, one of adsorption, desorption another adsorber regeneration, the desorption of contaminants catalytic combustion emptying.
Water-activated alumina defluoridation to try to avoid high temperatures because of the high temperature will reduce the amount of adsorption, absorption effect due to temperature rises. While avoiding high gas dust content, because dust clouds tar clog the pores of activated alumina supplier, increases drag, reducing adsorption effect, in this case, to install the device in front of the water dust activated carbon, in order to improve efficiency and service life .

Function of active alumina adsorbent

Automobile Desiccation Molecular Sieve has a number of capillary pores, surface area, can be used as adsorbent, desiccant and catalyst.Also determined according to the polarity of the adsorbed material strength, water, acetic acid, alkali oxides, has a strong affinity, activated alumina water depth is a desiccant and adsorbent for adsorption of polar molecules.

activated alumina catalyst for fluoride removal is similar to resin, but the fluoride ion-selective anion exchange resin, alumina adsorbent defluorination of good volume stability, 6400 grams per cubic metre of activated alumina fluorine.Alumina adsorbents with high strength, low wear, water, no soft, no swelling, no powder, no rupture.Can be widely used in the depth of the oil gas, ethylene-propylene gas drying and hydrogen, air separation units, instrument drying machine drying, fluoride in hydrogen peroxide treatment can remove sulfur gas emitted from hydrogen, sulfur dioxide, hydrogen fluoride, hydrocarbons and other pollutants, especially adapted water containing fluoride fluoride treatment.

Properties and uses of active alumina adsorbent

Activated alumina adsorbent is X-ρ-alumina adsorbents, white ball, strong adsorption capacity.Under certain operating conditions and regeneration under the condition of the dry depths of up to below dew point temperature-40 ℃, is a micro-depth water efficient desiccant for drying.Widely used in petrochemical industry of gas, liquid and dry, used in the textile industry, the oxygen industry automation instrument air drying, air separation by pressure swing adsorption.Because of the monomolecular adsorption layer net heat high, so it is very suitable for regenerative devices.

White spherical porous alumina adsorbent particle, uniform size, smooth surface, high mechanical strength, high moisture, do not swell after water absorption undivided in their natural state, product is nontoxic, tasteless, odorless, insoluble in water and organic solvents, is made of high purity alumina formed by scientific allocation, Molecular sieve adsorber catalyzed by finishing.It can be used as a fluorine-removal agent for high fluorine water, making a molecular adsorbent with high specific surface area.When the raw water PH value and alkalinity is low, the high fluoride removal capacity greater than 3.0mg/g.Plant and can be used for drinking water fluoride, arsenic and wastewater decolorization and deodorization.

Knowledge of the structure and characteristics of molecular sieve

Molecular sieve is a silicate or a crystalline aluminosilicate, and formed of silicon oxide or aluminum oxide tetrahedra linked by oxygen bridges tetrahedron. Molecular size (typically 0.3 ~ 2.0 nm) of the pore and cavity system, so as to have characteristics of solid molecules. However, with the synthesis and application of molecular sieve-depth study, researchers found that the aluminophosphate molecular sieves and sieve skeleton elements (silicon or aluminum or phosphorus) may be composed of B, Ga, Fe, Cr, Ge, Ti, V , Mn, Co, Zn, Be and Cu, substituted, its pore size and the cavity may reach 2 nm or more, the zeolite framework elements can be divided according to type aluminosilicate zeolite, Activated alumina adsorbent molecular sieves and molecular sieve framework heteroatoms ; divided by pore size, pore size of less than 2 nm, 2 ~ 50 nm and the molecular sieve is larger than 50 nm are referred to as micropores, mesopores and large pore molecular sieves. Because of the larger aperture size becomes larger carrier molecules react well, but the pore walls of mesoporous materials are amorphous, resulting in the hydrothermal stability and thermal stability still can not meet the required conditions for petrochemical applications demanding .
