The advantage of Molecular sieve absorption

molecular sieve manufacturers ability is very strong, for gas purification, save should avoid direct exposure to the air.Stored for a long time and has moisture-molecular sieve regeneration should be carried out before use.Molecular sieve avoiding oil and liquid water.Should be used as far as possible avoid contact with oils and liquid water.Drying in mole sieve dehydration of industrial gases, air, hydrogen, oxygen, nitrogen, argon and so on.Adsorption dryer with two parallel, a job, while the other can be regenerated.Alternating work and regeneration, to ensure a continuous operation.Dryer working at room temperature, impact regeneration in a heated to 350 degrees.

Molecular sieve

Molecular Sieve High Voltage is a kind of cubic lattice Silicon aluminate compounds, mainly composed of silica-alumina by oxygen bridges to connect empty skeletal structure, there are many uniform pore size in the structure of pores and neat, and a large internal surface area of the cavity.Also contains the price lower and larger Ionic radius of metal ions and combined state of the water.Due to water molecular in heating Hou continuous to lost, but Crystal skeleton structure not variable, formed has many size same of empty cavity, empty cavity and has many diameter same of micro-hole connected, these tiny of cavities diameter size uniform,activating molecular sieves can put than channel diameter small of molecular adsorption to cavities of internal in the to, and put than channel big have molecular exclusion out, thus can put shape diameter size different of molecular, polar degree different of molecular, boiling point different of molecular, saturated degree different of molecular separation from, that has "screening" molecular of role, Known as molecular sieves.Current molecular sieve in chemical, electronics, petrochemicals, natural gas is widely used in the industry.

Activated alumina has any effect

Improve the reactivity of alumina catalyst, activated alumina water treatment purity ultrafine activated alumina manufacturing method of the product is white or reddish small spherical particles, having a lot of pores and a higher activity, good governance fluoride water effects, easy regeneration, disruptors less, except for drinking water fluoride removal effect, it can also be used as an adsorbent, desiccant and catalyst carrier.
Widely used in water engineering, special water purification project, hydrogen peroxide plant, fertilizer plant, oxygen plant and petrochemical industries.

Activated alumina desiccant

This activated alumina manufacturer is a microporous globular substance, has a strong adsorption function, large surface area, high compressive hardness, long life, and through the regeneration method used repeatedly. White, spherical porous material, non-toxic, odorless, not powder, insoluble in water. Widely used in petrochemical, chemical, textile, metallurgical industries instrument air drying, pressure swing adsorption air separation unit adsorption dew point up to -41 degrees, it can also be used in the steel, oil cracked gas, ethylene, propylene The depth of the liquid and vapor drying.
Common Specifications: 3-5㎜ 4-6㎜ 5-8㎜

Activated alumina sorbent

White or red small spherical particles do not dissolve in water and other organic solvents, it has a strong adsorbent. Circulation mainly for the production of hydrogen peroxide in the hydrogen peroxide reproducing apparatus, adsorption working fluid in the water and impurities.
Activated alumina adsorption defluorination effect, stable capacity per cubic meter of active alumina suction fluorine 6400 g. This product has high strength, low wear, flooding the same soft, not inflated, not powder, not crack.
Uses: active alumina production patent news and information, activated alumina desiccant industry knowledge quiz, activated alumina sorbent improved method of activated alumina alumina catalyst is usually specifically referred to as "activated alumina water treatment", which is a porous, high dispersion of solid materials, a large surface area, which includes a microporous surface catalysis of the required characteristics, such as adsorption, surface activity, good thermal stability, so widely used as chemical reaction catalysts and catalyst supports.
Activated alumina having a plurality of capillary channels, large surface area, can be used as an adsorbent, desiccant and catalyst. Also according to the polarity of the adsorbed species to determine the strength of the water, oxides, acetic acid, alkali and other strong affinity, is a micro water depth of desiccant, adsorbent is adsorbed polar molecules. Activated alumina fluoride removal similar to the anion exchange resin, but the fluoride ion selective anion resin large.
Activated alumina industry knowledge, activated alumina factory patent, activated alumina industry, activated alumina desiccant
Activated alumina is the scope of alumina chemicals, mainly used adsorbents, purifying agent, catalyst and catalyst support, depending on the use of its raw materials and preparation methods.
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 .
