Guangzhou Special activated carbon for catalyst carrier Zeolite is a porous aluminosilicate crystal (a1uminsi1ict) with a water bearing frame structure, which exists naturally in nature and is also artificially synthesized. The ideal chemical formula of zeolite can be expressed as Mx/yA1XSiyO2 (x y) P? H2O, Where, M is alkali metal (such as Na, K, Li) and alkaline earth metal (such as Ca, Mg, Ba, Sr). The chemical composition of zeolite is generally considered to be composed of A12O3, SiO2, H2O and metal cations, of which A12O3 and SiO2 account for about 80% of the total zeolite minerals. In different zeolite minerals, the proportion of silicon and aluminum is different, Special activated carbon for catalyst carrier production And the different proportion of zeolite will cause some changes in zeolite characteristics, such as ion exchange and acid resistance. 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.

Special activated carbon for catalyst carrier high quality 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 equipment is hydrophobic. 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. The zeolite content of the zeolite runner is proportional to the adsorption concentration efficiency. Therefore, many people should pay more attention to whether the zeolite content of the equipment meets the requirements or is high enough when choosing to purchase the zeolite runner. On the one hand, selecting excellent equipment is also to enhance the potential value of the enterprise. Special activated carbon for catalyst carrier Guangzhou The adsorption and concentration technology of zeolite runner is deeply loved by enterprises because of its high efficiency and energy saving characteristics. Its changeable working environment and low cost have laid an unshakable position for zeolite runner in industry. How to select a zeolite runner with stable operation and high efficiency needs people's eyes

Special activated carbon for catalyst carrier high quality The mutual adsorption between molecules is also called "van der Waals gravity". Although molecular motion speed is affected by temperature, material and other reasons, 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. Physical adsorption mainly occurs in the process of removing impurities from the liquid and gas phases of zeolite. The porous structure of zeolite provides a large amount of specific surface area, which makes it very easy to absorb and collect impurities. Due to the interaction of molecules, a large number of molecules on the pore wall of zeolite can generate strong gravity, just like magnetic force, So as to achieve the purpose of attracting impurities in the medium to the aperture. Special activated carbon for catalyst carrier Guangzhou Chemical adsorption 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 of earth or complexes that can react with the adsorbed substances, and then combine with the adsorbed substances to gather inside and on the surface of zeolite.

Special activated carbon for catalyst carrier production 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, is characterized by 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 can be regenerated at high temperature. Compared with honeycomb activated carbon, its performance is about 25% of its efficiency, However, it is widely used in the fields of adsorption, separation, catalysis and environment due to its high temperature resistance and difficult ignition, Special activated carbon for catalyst carrier high quality It is more suitable for the treatment of organic waste gas with large air volume and low concentration.

Special activated carbon for catalyst carrier Guangzhou 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. Special activated carbon for catalyst carrier 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.
