Honeycomb zeolite molecular sieve purchase 1. From the composition of both, carbon molecular sieve is an excellent non-polar carbon material, while zeolite molecular sieve is a hydrate of crystalline aluminosilicate metal salt. The two are completely different in the periodic table of chemical elements! 2. With different pore sizes, the pore composition of zeolite molecular sieves is clearly registered, which can be generally divided into macropores, mesopores and micropores, and there are interconnections between the pores, while carbon molecular sieves are generally micropores! 3. The adsorption principle is different. Zeolite molecular sieves absorb molecules of certain size and repel molecules of larger substances. Honeycomb zeolite molecular sieve Henan Carbon molecular sieve contains a large number of micropores, which can effectively separate the components of gas mixture. 4. The uses are also different. Carbon molecular sieves are widely used in coal fields, petroleum, chemicals, metal heat treatment, electronic manufacturing, food preservation and other industries, while zeolite molecular sieves can be used in addition to petroleum, chemicals, natural gas, electronic production, industrial gas separation, pharmaceutical industry, refrigeration industry, and hollow glass manufacturing.

Honeycomb zeolite molecular sieve Henan The adsorption and concentration technology of zeolite runner is highly praised by enterprises because of its high efficiency and energy saving. Its changeable working environment and low cost ensure the popularization and application of zeolite runner in industry. How to select a zeolite runner with stable operation and high efficiency? The zeolite content of the zeolite runner is proportional to the adsorption concentration efficiency. Therefore, when choosing to purchase the zeolite runner, the matching zeolite content should be selected in combination with the emission concentration of the enterprise's exhaust gas pollutants. Zeolites with large specific surface area shall be purchased for good hydrophobicity. Select the inspection equipment to test the hydrophobicity of the equipment. When the air humidity is greater than 60%, calibrate the equipment. If the equipment is blocked and the machine works abnormally, it indicates that the equipment has poor hydrophobicity, and you should carefully consider whether to purchase the equipment. The factors affecting the purification efficiency of zeolite due to high desorption efficiency are: absorption on the one hand and desorption function on the other. Honeycomb zeolite molecular sieve purchase If the waste gas adsorbed on the runner cannot be completely desorbed, the runner will become saturated after a long time, which will affect the adsorption efficiency of the zeolite runner and directly affect the service life of the zeolite over time.

Because there are uniform small internal pores in the molecular sieve structure, Honeycomb zeolite molecular sieve Henan When the molecular linear degree of reactants and products is close to the pore size of the crystal, the selectivity of catalytic reaction often depends on the corresponding size of the molecule and pore size. This selectivity is called shape selective catalysis. There are two mechanisms leading to shape selectivity. One is caused by the difference of diffusion coefficient of molecules participating in the reaction in the pore cavity, which is called mass transfer selectivity; The other is caused by the space limitation of the transition state of the catalytic reaction, which is called transition state selectivity. Molecular sieve has clear pore cavity distribution, extremely high internal surface area (600m2/s), good thermal stability (1000 ℃), and adjustable acid site center. The acidity of molecular sieve mainly comes from three coordinated aluminum atoms and aluminum ions (AlO)+on the framework and in the pores. The OH based acid sensitive site center on the molecular sieve HY obtained by ion exchange, and the aluminum ion outside the framework will strengthen the acid site, forming the L acid site center. Polyvalent cations such as Ca2+, Mg2+and La3+can show the acid site center after exchange. The reduction of transition metal ions such as Cu2+and Ag+can also form acid site centers. In general, the higher the Al/Si ratio, the higher the specific activity of OH group. The modification of zeolite acidity can introduce protons through direct exchange of dilute hydrochloric acid. Honeycomb zeolite molecular sieve purchase This method often leads to dealumination of molecular sieve framework. So NaY will become NH4Y and then HY.

The main material of honeycomb zeolite molecular sieve is natural zeolite, which is an inorganic microporous material composed of SiO2, Al2O3 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 300-1000 m2/g, which has the characteristics of high temperature resistance, non flammability, good thermal stability and hydrothermal stability, Honeycomb zeolite molecular sieve Henan It is an efficient molecular sieve carrier with good adsorption performance, no secondary pollution, and can be regenerated at high temperature. Its efficiency is 40% higher than that of similar activated carbon. It is widely used in the fields of adsorption, separation, catalysis and environment, and is more suitable for the treatment of organic waste gas with large air volume and low concentration. Honeycomb zeolite molecular sieve purchase The adsorption material has a stable ozone decomposition ability, which significantly improves the decomposition efficiency of VOCs. The adsorption material first forms a special structural effect through the combination design of silver and manganese, which can decompose ozone into active oxygen atoms, and then react with VOCs molecules to form carbon dioxide and water.
