Introduction To Honeycomb zeolite molecular sieve

The main material of honeycomb 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 300-100m2 / g. It has the characteristics of high temperature resistance, nonflammability, good thermal stability and hydrothermal stability, it is a kind of inorganic microporous material with good adsorption performance and no secondary pollution. the high-efficiency molecular sieve carrier that can be regenerated at high temperature improves the efficiency by 40% compared with similar activated carbon. It is widely used in the fields of adsorption, separation, catalysis and environment. It is more suitable for the treatment of organic waste gas with large air volume and low concentration.

Classification of Honeycomb Zeolites And Molecular Sieves

Zeolite molecular sieve products include microporous molecular sieve and mesoporous molecular sieve.

(1) Microporous molecular sieve with molecular pore diameter less than 2mm and mesoporous molecular sieve with molecular pore diameter of 2-50nm (macroporous molecular sieve with molecular pore diameter more than 5onm). Mesoporous molecular sieve has the characteristics of high specific surface area, regular and orderly pore structure, narrow pore size distribution and continuous adjustable pore size, which makes it difficult to complete the adsorption and separation of macromolecules in many microporous molecular sieves and catalytic reaction.

(2)Therefore, molecular sieve materials with different properties and pore sizes should be configured according to the different components of organic waste gas, so as to achieve target organic waste gas treatment, meet the design requirements and emission standards.

Application of Honeycomb Zeolite Molecular Sieve

Zeouite molecular sieve is a very excellent adsorbent, which is widely used in the production of basic organic chemical industry and petrochemical industry. In the treatment of harmful gases, it is also used for the purification of so2, nox, co, co2, nh3, cci4, steam and gaseous hydrocarbon waste gas, as well as the air purification, deodorization and odor adsorption of flue gas, removal of mercury vapor,etc.

Prominent Advantages of Honeycomb Zeolite Molecular Sieve

1.Strong adsorption selectivity. The pore size of molecular sieve is neat and uniform, and it is also an ionic adsorbent,therefore, it can selectively adsorb according to the size and polarity of molecules, effectively remove ethylene and propylene from saturated hydrocarbons and acetylene from ethylene, which is determined by its strong polarity.

2.Strong adsorption capacity. Even if the composition concentration of the gas is very low,it still has adsorption capacity,

3.It is less affected by temperature and still has great adsorption capacity at higher temperature, while other adsorbents are greatly affected by temperature.

4.It can be regenerated at high temperature, with high regeneration efficiency and high safety,

5.Strong toxicity resistance and good thermal stability
