Small block activated carbon Hubei 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. Small block activated carbon manufactor 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.

Small block activated carbon major With the deepening of research, zeolite molecular sieves have gradually moved from laboratory to industrial application. Due to its powerful performance, it can be integrated with the reactor. In membrane catalytic reaction, reaction and separation are coupled. At present, the application fields of zeolite membrane are pervaporation, gas separation and membrane reactor. It is the needs of human practical activities and the development of application fields that constantly promote the development of zeolite molecular sieves. From natural zeolite to synthetic zeolite, from low silica zeolite to high silica zeolite; From silicoaluminium molecular sieve to aluminophosphate molecular sieve; From super micropore to mesoporous material; From inorganic porous frameworks to MOFs, and recently emerging macroporous materials, the yield has been effectively improved, and the synthesis cost and environmental pollution have been reduced
Small block activated carbon major Because the silicon (aluminum) oxygen tetrahedron of natural zeolite crystal has many holes and channels, which occupy cations and water molecules. When some other goods are completely dehydrated after baking, the crystal skeleton is not damaged, but forms large holes on the inner surface, which can absorb and store a large number of molecules, so it has the characteristics of large adsorption capacity and high selectivity. 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. Small block activated carbon manufactor In different zeolite minerals, the proportion of silicon and aluminum is different, and the different proportion will cause some characteristics of zeolite changes, such as ion exchange and acid resistance.
Small block activated carbon major Microporous molecular sieves with molecular pore size below 2 nm and mesoporous molecular sieves with molecular pore size between 2-50 nm (50 nm The above are macroporous molecular sieves), 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 play an important role in the adsorption, separation and catalytic reaction of macromolecules that are difficult for many microporous molecular sieves to complete. 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 Small block activated carbon Hubei 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.
