Molecular Sieve, also known as zeolite or mol sieve, is made of crystalline aluminosilicate with SiO2: AI202 in the ratio of 2:1. Formed through the extensive cross-linking between AIO4 and SiO4 tetrahedra, this results in different pore openings which determine the type of Molecular Sieve. It is available in different forms such as pellet, powders, and spheres to help meet the various needs of different applications and industries. Molecular Sieves are desiccants with high absorption capacity, mechanical strength, and very low attrition loss.
How does Molecular Sieve work?
The customised pore openings allow specific molecules to be separated from one another by absorbing those that are smaller than the diameter of the pore openings while excluding the rest. This process makes the dehydrating, purifying, and separating of selective gas & liquid substance greatly possible. Capable of absorbing up to 22% of its weight, it is also commonly used in Filtration Systems or as desiccant sachets to reduce humidity levels. Able to function at even a high temperature of 300ºC, the adsorbent is suitable for machinery applications. Furthermore, the different pore openings enable the Molecular Sieve to function in various applications, making the product robust and multi-purpose. It can also be regenerated at high temperatures when exposed to moisture over a long duration. To restore the absorbent to full capacity, simply heat it to an optimal temperature between 130ºC – 250ºC. However, this temperature differs for each type of Molecular Sieves.
