Honeycomb zeolite molecular sieve is a kind of aluminosilicate material containing alkali metal or alkaline earth metal oxide with open framework and regular pore cage structure. It has been widely used since it was discovered by Swedish scientists in 1956, and then it has been widely used in petrochemical industry, environmental protection, bioengineering and other fields due to its special physical characteristics. Wood activated carbon major And with the gradual expansion of the demand for zeolite molecular sieves, researchers began to expand a variety of synthetic methods of zeolite molecular sieves to meet the needs of various fields. Zeolite molecular sieve has super strong adsorption performance, which is due to a "surface force" generated by molecular gravity on the solid surface. When the fluid flows, some molecules in the fluid collide with the adsorbent surface due to irregular movement, resulting in molecular concentration on the surface, reducing the number of such molecules in the fluid to separation Purposes of clearing. Wood activated carbon manufactor Since the adsorption does not undergo chemical changes, as long as the molecules concentrated on the surface are managed to drive away, the zeolite molecular sieve will have the adsorption capacity again. This process is the reverse process of adsorption, which is called the resolution or regeneration process.

Wood activated carbon major Rely on its own unique void structure. The pore size of zeolite is uniform, the internal void structure is developed, the specific surface area is large, the adsorption capacity is strong, and contains a large number of invisible pore sizes. The pore size in 1g zeolite material can be expanded to the specific surface area of 500-1000m2, which is higher for special purposes. The mutual adsorption between molecules is also called "van der Waals gravity". Although molecular motion speed is affected by temperature, material and other factors, Wood activated carbon manufactor But it always keeps moving in the micro environment. Due to the mutual attraction force between molecules, when a molecule is trapped in the inner pore volume of zeolite, it will lead to more molecules being absorbed until the adsorption of zeolite is saturated.

The pore size in 1g zeolite material can be expanded to the specific surface area of 500-1000m2, which is higher for special purposes. The main material of honeycomb zeolite adsorbent is natural zeolite. The zeolite manufacturer is an inorganic microporous material composed of sio2, al_2o_3 and alkaline metal or alkaline earth metal. Its inner pore volume accounts for 40-50% of the total volume, and its specific surface area is 100-500 m2/g, Wood activated carbon Fujian It has the characteristics of high temperature resistance, incombustibility, good thermal stability and hydrothermal stability. It is an efficient molecular sieve carrier with good adsorption performance, no secondary pollution, and can be regenerated at high temperature. Compared with honeycomb activated carbon, its performance is about 25% of its efficiency. However, it has the characteristics of high temperature resistance, difficult ignition, etc. It is widely used in the fields of adsorption, separation, catalysis and environment, and is more suitable for large air volume Low concentration organic waste gas treatment.

The pore size in 1g zeolite material can be expanded to the specific surface area of 500-1000m2, which is higher for special purposes. Good hydrophobicity The evaluation of the adsorption of zeolite depends not only on whether the specific surface area of zeolite is large enough, but also on whether the hydrophobicity of equipment is good. Wood activated carbon Fujian When purchasing, people can choose the inspection equipment. When the air humidity for the hydrophobicity of the inspection equipment is greater than 60%, if the equipment is blocked and the machine works abnormally, people should carefully consider whether to purchase the equipment. It is important to know that the adsorption and hydrophobicity of the zeolite runner are equally important. 3、 High desorption efficiency The purification efficiency of zeolite is determined by absorption on the one hand and desorption function on the other, Wood activated carbon major If the desorption efficiency of the equipment cannot meet the daily operation standard, the working efficiency of the zeolite runner will be affected if the time is long. Not only that, it will also affect the zeolite runner.

Honeycomb zeolite molecular sieve has the crystal structure and characteristics, the surface is a solid skeleton, and the internal holes can play the role of adsorption molecules. There are channels between the holes to connect with each other, and molecules pass through the channels. Due to the crystalline nature of the pores, the pore size distribution of the molecular sieve is very uniform. Molecular sieves selectively adsorb molecules according to the size of holes in their crystals, that is, they adsorb molecules of a certain size and repel molecules of larger substances, so they are vividly called "molecular sieves". The adsorption or repulsion function of molecular sieves is affected by the molecular electricity. Synthetic zeolite has the special function of selective adsorption according to molecular size and polarity, Wood activated carbon manufactor Therefore, gas or liquid can be dried or purified, which is also the basis for molecular sieve separation. Synthetic zeolite can meet the extensive demand of industry for adsorption and selective products, Fujian Wood activated carbon It is also widely used in industrial separation to synthesize zeolite molecular sieves. Advantages of UOP molecular sieve

Wood activated carbon major The highly effective selective adsorption is due to the fact that the alumina tetrahedron of zeolite has a negative charge, while the skeleton hole contains cations, which forms a strong electric field around the cations. Therefore, the adsorption force of zeolite not only has a strong dispersion force, but also has a large electrostatic force. It is precisely because of this electrostatic relationship that zeolites have preferential selective adsorption on polar, unsaturated and polarizable molecules. It can strongly adsorb molecules containing polar groups such as hydroxyl ion, ammonium ion and other polarizable groups, especially water, which can form hydrogen bonds with aluminum silicon skeleton, so zeolite has strong water absorption. It can still adsorb even under low relative humidity and concentration, and its water absorption is higher than that of silica gel and activated alumina. The adsorption capacity of zeolite for organic pollutants mainly depends on the polar size and molecular diameter of organic molecules. Small molecules are easier to be adsorbed than large molecules, while polar molecules are easier to be adsorbed than non-polar ones. Different substances (such as organic molecules, metal ions and water molecules) exist in water, Wood activated carbon manufactor Their polarity and molecular size are different, and competition will occur during adsorption.
