Coconut shell activated carbon Pingxiang Zeolite molecular sieve is a kind of excellent adsorbent, which is widely used in the production of basic organic chemical industry and petrochemical industry, as well as in the treatment of harmful gases nox、co、co2，nh3，ccl4、 Purification of water vapor and gaseous hydrocarbon waste gas; As well as air purification and deodorization in biochemical industry, paint industry, underground places, leather factories and animal breeding places; Adsorption of flue gas odor, removal of mercury vapor, etc. Strong adsorption selectivity. The pore size of molecular sieve is uniform, and it is also an ionic adsorbent. Therefore, it can selectively adsorb according to the size and polarity of molecules. It can effectively remove ethylene, propylene and acetylene from saturated hydrocarbons, which is determined by its strong polarity. Coconut shell activated carbon production In addition to physical adsorption, chemical reaction also often occurs on the surface of zeolite, which contains a small amount of chemical combination, oxygen and hydrogen in the form of functional groups. These surfaces contain oxides or complexes that can react with the adsorbed substances, so that they can combine with the adsorbed substances and aggregate to the interior and surface of zeolite.

Coconut shell activated carbon purchase 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, Coconut shell activated carbon production 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.

High silica zeolite type molecular sieves, this kind of zeolite has a series, and ZSM-5 is widely used, with ZSM-8 and ZSM-11 having the same structure; The other group is ZSM-21, ZSM-35 and ZSM-38. ZSM-5 is often called high silica zeolite, with the Si/Al ratio up to 50 and ZSM-8 up to 100. This group of molecular sieves also shows hydrophobic characteristics. Coconut shell activated carbon production Their structural units are similar to those of mordenite, consisting of pairs of five membered rings, with no cage like cavities and only channels. ZSM-5 has two sets of cross channels, one is straight through, the other is zigzag perpendicular to each other, both formed by ten yuan rings. The channel is oval and its window diameter is (0.55-0.60) nm. Coconut shell activated carbon purchase Zeolites belonging to the high silicon group also have silicalite-1 of all silicon type, which has the same structure as ZSM-5, and silicalite-2 is the same as ZSM-11.

Coconut shell activated carbon purchase Microporous molecular sieves with molecular apertures below 2 nm, mesoporous molecular sieves with molecular apertures above 50 nm (macroporous molecular sieves with molecular apertures above 50 nm), mesoporous molecular sieves have high specific surface area, regular and orderly pore structure, narrow pore size distribution, continuous and adjustable pore size and other characteristics, which make it difficult to complete the adsorption and separation of macromolecules in many microporous molecular sieves, And catalytic reaction. Therefore, molecular sieve materials with different properties and pore sizes shall be configured according to the different components of organic waste gas during selection, so as to achieve targeted organic waste gas treatment, meet the design requirements and emission standards. The main material of honeycomb zeolite adsorbent is natural zeolite. The manufacturer of zeolite is composed of silica Inorganic microporous material composed of al_2o_3 and alkaline metal or alkaline earth metal, with inner pore volume accounting for 40-50% of the total volume and specific surface area of 100-500 m2/g, has the characteristics of high temperature resistance, non flammability, good thermal stability and hydrothermal stability. It is an efficient molecular sieve carrier with good adsorption performance, no secondary pollution, and high temperature regeneration. Compared with honeycomb activated carbon, its performance is about 25% of its efficiency Coconut shell activated carbon Pingxiang However, it is widely used in the fields of adsorption, separation, catalysis and environment due to its high temperature resistance and low ignition resistance. It is more suitable for the treatment of organic waste gas with large air volume and low concentration.

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. 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. Coconut shell activated carbon Pingxiang 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, Coconut shell activated carbon purchase 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.

Coconut shell activated carbon Pingxiang There are cavities and channels in the crystal structure of zeolite with large adsorption capacity, whose volume accounts for more than 50% of the total volume of zeolite crystals. Moreover, the micropores of zeolite are evenly distributed, and the pore size is small, which is equivalent to the molecular size of general substances. The internal surface area of zeolite crystals can reach more than 1000 square meters. Therefore, the adsorption capacity of zeolite is particularly large. The holes and channels inside the highly selective zeolite crystal are uniform and fixed in size, and the diameter of the holes is generally 6~15A. Coconut shell activated carbon production Only molecules with smaller diameter can enter the cavity through the zeolite channel and be adsorbed, while large molecules cannot enter the cavity and be adsorbed. Zeolite is also called molecular sieve because of its selective adsorption performance. However, silica gel, activated carbon and other adsorbents have no selective adsorption and screening performance due to their non uniformly fixed pore sizes and large changes.
