I. Product introduction
3A molecular sieve adsorbent is a kind of spherical or strip KA type adsorbent with microporous structure:
* The optimized distribution of bore diameters makes adsorption capacity higher.
* The regular structure of bore passages increases adsorption velocity and reduces the height of mass transfer zone
* The materials with large specific surface area can extend the service life of adsorbent bed.
II. Technical introduction
Zeolite 3A bore diameter is close to 3Å, which cannot absorb the molecules with a larger diameter than 3Å. It is mainly used for water adsorption. The shape and structure optimization resulted in the high selectivity, greater adsorption velocity as well as higher crushing strength and anti-pollution ability, which improves the utilization efficiency of the molecular sieve and extends its service life. It is the preferred desiccant for deep drying, purifying and refining of hydrocarbon materials in gas and liquid phase.
