Category: Molecular sieves

Molecular sieve is a synthetic hydrated aluminosilicate (zeolite) or natural zeolite with the function of screening molecules.Zeolite molecular sieve has a complex and changeable structure and a unique pore system, and is a catalyst with excellent performance.

Uses of Molecular Sieves

Molecular sieve is mainly caused by molecular attraction, which produces a “surface force” on the fixed surface. When the fluid flows through, some molecules in the fluid will make irregular movements and collide with the surface of the adsorbent. Molecular concentration occurs on the surface, and in the overall collision motion, the number of molecules is reduced, so as to achieve the effect of separation.

Molecular Sieve for VOCs

/ / no Comments

About Molecular Sieve for VOCs:
 

Molecular sieve for VOCs is our latest developed product, a new generation of special molecular sieve for adsorption of volatile organic compounds (VOCs).

It is hydrophobic and organophilic, suitable for the adsorption and separation of VOCs from industrial exhaust gas, especially suitable for the separation and recovery of organic matter from industrial exhaust gas containing more water vapor.  

It has good thermal stability and hydrothermal stability, stable structure, uniform pore, adsorption and desorption speed, easy regeneration, non-combustion, long service life and other advantages, which could replace the traditional carbon materials (activated carbon, activated carbon fiber, etc.).

 

It has developed three-dimensional medium microporous channels, which is suitable for adsorption of small and medium molecular VOCs with molecular sieve size less than 0.55nm, but not for adsorption of larger molecular VOCs.  Typical VOCs applicable to this product include: toluene, xylene, styrene, hexane, cyclohexane, acetone, ethyl acetate, methanol, ethanol, propanol, butanol, phenol, formaldehyde, acetaldehyde, etc. 


RBOSCHCO is a trusted global supplier of Molecular Sieve for VOCs. We provide zeolite molecular sieve, molecular sieve 3a, molecular sieve 13x, molecular sieve 4a, molecular sieve 5a, lithium molecular sieve, oxygen molecular sieve. Feel free to send an inquiry to get the latest price, if you would like to buy in bulk.
