Understanding the fundamental science behind our products is key to appreciating their capabilities. At NINGBO INNO PHARMCHEM CO.,LTD., we leverage the principles of selective adsorption with our advanced 5A molecular sieves to achieve precise gas separation in various industrial applications.

A molecular sieve, like our 5A type, is a crystalline material characterized by a network of uniform pores. The '5A' designation refers to the effective pore opening size, which is approximately 5 angstroms (0.5 nm). This specific pore size is the secret to its selective adsorption power. Molecules with a kinetic diameter smaller than 5 angstroms can enter the pores and be adsorbed onto the internal surface of the sieve, while molecules larger than this threshold are excluded.

This principle of size exclusion is vital for processes such as the separation of normal- and iso-paraffins in the petrochemical industry. Normal paraffins are linear molecules that can fit into the 5A sieve's pores, while branched or cyclic hydrocarbons, being larger, are kept out. This allows for the efficient isolation of specific hydrocarbon fractions.

The same selective adsorption mechanism is employed in hydrogen purification molecular sieve 5A. Impurity molecules like water, CO2, and H2S are adsorbed, leaving high-purity hydrogen. Similarly, in oxygen concentrator molecular sieve 5A systems, nitrogen is adsorbed, allowing oxygen to pass through, thus enriching the oxygen concentration.

The scientific understanding of these adsorption processes also informs the regeneration strategies for our 5A molecular sieves. By understanding the affinity of different molecules for the sieve and the energy required to desorb them, we can optimize regeneration cycles. This ensures that the sieve can be reused effectively, maintaining its performance for critical applications like molecular sieve for gas separation.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing adsorbents that not only perform exceptionally but are also backed by a deep understanding of the underlying science. Our 5A molecular sieves are a prime example of harnessing precise molecular interactions for industrial advancement.
