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 zeoliteActivated 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 .

Molecular sieve and activated alumina What is the difference

activating molecular sieves and activated alumina belong to the same industrial sorbent adsorption mechanism are the same, in general do-liquid adsorption, molecular sieve and activated alumina in general with the use of activated alumina general points in the lower part of the purification do pretreatment, molecular sieves Late relatively fine purification for adsorption.Molecular sieve absorption ability, for the purification of gas, should be saved to avoid direct exposure to the air. Should be reproduced before the molecular sieve and has longer storage time of use of the absorbent. Zeolite avoid oil and liquid water. Should be used to avoid contact with the oil and liquid water. Activated alumina ball is mainly used in chemical, metallurgy, electronics, oil and other industrial gases such as dried air, oxygen, nitrogen and other permanent gases smelt gas and oil cracking gas. I produced the activated alumina is a multi-pore, high-intensity x-ρ-alumina product  have a strong affinity for water is a water depth of desiccant drying trace. Use medium has soaked in water the same soft, not inflated, not powder dry phase characteristics, textile industry, oxygen and industrial automation instrument air dry. 13X molecular sieve adsorption equilibrium static water can reach about 23%. Activated alumina 17% of the way.

Molecular sieve type oxygen machine works:

Process for the two towers. After feed air pressurized by the compressor, through the air pretreatment means to remove oil, dust and other solid impurities and water, and cooled to room temperature, treated by the compressed air through the intake valve into the Activated alumina adsorbent containing a molecular sieve, the air nitrogen, carbon dioxide is adsorbed effluent gas is the high purity oxygen, Tada when adsorbed to a certain saturation, the intake valve closed, the flush valve opens, the adsorption tower into the rinse stage, after the flush valve is closed, the valve opens desorption into the desorption regeneration phase, so that a complete cycle.
