The performance of the natural gas desiccant

natural gas desiccant as the powder crystal, with metallic luster, hardness is 3 ~ 5, the relative density of 2 ~ 2.8, the natural zeolite has a color, synthetic zeolite is white, insoluble in water, thermal stability and acid resistance increased with the increase of SiO2 / Al2O3 ratio increased. Molecular sieve has a large specific surface area, 300 ~ 300 m2 / g, the highly polarized crystal surface, as a kind of efficient adsorbent, is also a kind of solid acid, surface has high concentration of acid and acid strength, can cause is catalytic reaction of carbon ionic. When the composition of the metal ion and other ions in the solution during the exchange, adjustable aperture, change its adsorption properties and catalytic properties, which made the performance of different molecular sieve catalyst.

double glazing window glass desiccant has faster adsorption speed, more number of regeneration, high crushing strength and ability to resist pollution, improve the utilization efficiency of the molecular sieve and prolong the service life of molecular sieve, molecular sieve 3 a dry gas liquid phase depth is petroleum, chemical industry, refining, necessary choice of desiccant polymerization.

natural gas drying

double glazing desiccant has two kinds of natural zeolite and synthetic zeolites. (1) most of the natural zeolite by volcanic tuff and gray matter in the Marine sedimentary rocks coagulation or react to form in the lacustrine environment. Has now found that more than 1000 kinds of zeolite ore, more important is 35 kinds, common clinoptilolite and mordenite, erionite and ling zeolite, etc. Mainly distributed in the United States, Japan, France and other countries, China is also found that there is a lot of mordenite and clinoptilolite deposits, Japan is the largest country in the production of natural zeolite. (2) by natural zeolite resource constraints, starting in the 1950 s, a large number of the synthetic zeolite.

The performance of the molecular sieve

molecular sieve xh-5 as the powder crystal, with metallic luster, hardness is 3 ~ 5, the relative density of 2 ~ 2.8, the natural zeolite has a color, synthetic zeolite is white, insoluble in water, thermal stability and acid resistance increased with the increase of SiO2 / Al2O3 ratio increased. molecular sieve xh-9 has a large specific surface area, 300 ~ 300 m2 / g, the highly polarized crystal surface, as a kind of efficient adsorbent, is also a kind of solid acid, surface has high concentration of acid and acid strength, can cause is catalytic reaction of carbon ionic. When the composition of the metal ion and other ions in the solution during the exchange, adjustable aperture, change its adsorption properties and catalytic properties, which made the performance of different molecular sieve catalyst.

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.

In the field of biological macromolecules, common have a bio - preinstalled rad SEC molecular sieve column.

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".

molecular sieve activation

The molecular sieve activation adsorption or exclusive affected by molecular electrical function. Synthetic zeolite is according to the size of the molecules and polarity and the special function of selective adsorption, thus it can be to dry or purification of gas or liquid, this also is the basis of molecular sieve can be separated. Synthetic zeolite can meet the demand for adsorption and choose product features extensive industry, in industrial separation is also a large number of application to the synthesis of zeolite molecular sieves.

activated alumina water treatment has a great effect on catalytic science and technology. The invention of the '60 s molecular sieve cracking catalyst, triggered a technology revolution of oil refining industry. In the 70 s found that the shape-selective ZSM - 5 zeolite, makes the important petroleum refining and petrochemical industry a new industrial process (ethyl benzene, toluene disproportionation production, heavy oil dewaxing, etc.) development success. 80 s delay elements heteroatomic TS - 1 the double glazing desiccant molecular sieve catalytic oxidation "active field. In recent years, molecular sieve in "environmental catalytic application is also developing quickly. The successful application of molecular sieve in industrial catalysis process inspired molecular sieves synthesis, modification, characterization and application research of extensive. Molecular sieve modified the most basic way is through the secondary synthesis, impurity atoms with crystal to replace, change its skeleton. AEM for detection of nanoscale range of elements and their changes. Below by dealuminated Y zeolite molecular sieves and TS - 1 as an example, introduces the application of AEM in molecular sieves synthesis.
