natural gas adsorbent

natural gas adsorbent is a cubic lattice silicon aluminate compound. The microporous structure of the molecular sieve is uniform, and its cavity diameter size uniform, can the cavity is smaller than the diameter of the molecular adsorption to the interior of the pore space, and the polar molecules and unsaturated molecules have preferential adsorption ability, thus can bring a different polarity degree, degree of saturation is different, different molecular size and the boiling point of different molecular separation, which have the function of the "screening" molecules, therefore calls the molecular sieve. Because the molecular sieve separation has high adsorption capacity, strong thermal stability and other advantages of adsorbent is not makes the molecular sieve to obtain a wide range of applications.

American scientists have found that by adjusting the temperature, can precisely control holes the size of a titanium silicate material, to create sophisticated new molecular sieve. Some crystal materials have large internal uniform pores, size than small molecules can pass through the hole, and not through the large molecules, so you can have the effect of separation of different molecules, this kind of material is known as molecular sieve.

The working principle of molecular sieve xh-11

Adsorption function: molecular sieve xh-11 of matter from the physical adsorption (van der Waals force), the crystal inside the cavity has a strong polarity and coulomb field, the polar molecules (water) and unsaturated molecules exhibit strong adsorption ability.

Sieving function: double glazing molecular sieve pore size distribution is very uniform, only the molecular diameter smaller than the diameter of the cavity material made it into the zeolite crystal inside the cave.

Through adsorption priorities and the size to distinguish between different materials of molecules, so the image of a called "molecular sieve".

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 .

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.

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.

Specialty alumina activated alumina ball is applied to a set of properties of petrochemical, fertilizer and other industries as catalysts or catalyst supports large differences unique products. According to the nature or purpose may be divided into a number of brands and models, and its high-tech manufacturing process, and therefore economic benefits are substantial. Quality products in the market price per ton ranging from 10,000 to 100,000 yuan level number. However, some high-end products currently can not produce or no large-volume manufacturers, domestic manufacturers use to spend a lot of foreign exchange to import such products. Currently there are some manufacturers may be some small batch of high-end products, the product quality is close to the level of foreign investment as long as people pay attention and appropriate, high-grade production is entirely possible. Can then homegrown, even export to earn foreign money. State sintered alumina production of specialty alumina manufacturer has four decades of history, the brand has over a hundred varieties of species, can be summarized as aluminum hydroxide series, to be boehmite series, activated alumina series, calcined Alumina, high-purity alumina series aluminum calcium cement and its derivatives series and molecular sieves series. These products are widely used in various industries, is closely related to the development of the national economy. Specialty alumina refers to non-metallurgical alumina, and the output is a special processing of the unique nature of the economic benefits the rich or alumina hydrate. Specialty alumina for low grade bauxite resource-poor producers, especially for the relatively high cost of the sintering process manufacturers, undoubtedly develop production, improve efficiency, increase employment opportunities of a road. Therefore, the development of specialty alumina should arouse people's attention.

Modern water activated alumina is white spherical porous particles, uniform size, smooth surface, high mechanical strength, moisture absorption, no swelling after absorbing maintain the status quo does not crack, non-toxic, odorless, insoluble in water, ethanol, fluorine has a strong adsorption, mainly for high fluoride areas of fluoride in drinking water.
