Molecular Sieve 3a 4a 5a 13x And Zeolite Molecular Sieve Price For Adsorbent Dehydration
Product Description
Molecular sieve is a kind of synthetic molecular screening of hydrated silicon aluminate (zeolite) or natural zeolite, it has a lot of aperture on the structure of concreted complete neat rows of the cavity, different aperture of molecular sieve to separate different molecular size and shape. Molecular sieves with different pore sizes were obtained according to the molecular ratios of SiO2 and Al2O3. The models are: 3A(potassium A type), 4A(sodium A type), 5A(calcium A type), 13X(sodium X type), etc. It has high adsorption capacity, high selectivity and high-temperature resistance. It is widely used in organic and petrochemical industries and is also an excellent adsorbent for gas dewatering. More and more attention has been paid to waste gas purification.

Product Performance
a. Adsorption performance
The adsorption of zeolite molecular sieve is a physical change process. Gravity causes of adsorption is mainly molecules in the solid surface to produce a "surface force", when the fluid flows through some of the fluid molecules due to the collision and irregular exercise to the surface of adsorbent, the surface molecules together, reduce the number of molecules in fluid, achieve the purpose of separation, remove.
b. Ion exchange performance
In general, ion exchange refers to the exchange of compensated cation outside the zeolite molecular sieve framework. Compensation outside of zeolite molecular sieve skeleton ion is usually protons and alkali metal or the alkaline earth metal, they are easily in metal salt aqueous solution by ion exchange into various valence metal ionic type zeolite molecular sieve.
c. Catalytic performance
Most zeolites have strong acid centers on the surface of zeolite molecular sieves. These properties make it an excellent catalyst.
Product Uses
According to the specifications, the application of molecular sieve is as follows:
3A molecular sieve is mainly used as the desiccant in the chemical industry, petroleum industry, medicine industry, and medium-control glass industry.
4A molecular sieve is mainly used for the drying of chemical gases, liquids, refrigerants, pharmaceuticals, electronic materials and volatile substances.
5A molecular sieve is mainly used for the drying and refining of chemical, petroleum, natural gas, oxygen and other industrial gases.
The 13X molecular sieve is mainly used for general another drying, purification of raw gas of air separation units (removal of H20 and CO2), and desulfurization of liquid hydrocarbon and natural gas (removal of H2S
and thiols).
