Molecular sieves are crystalline porous materials, a type of synthetic zeolite, widely recognized for their precise and uniform pore structures. This unique characteristic makes them highly effective adsorbents and separators for a wide range of molecules based on size and polarity. Their critical role spans various industrial sectors, including petrochemicals, natural gas processing, air separation, and more, where efficient drying, purification, and separation are paramount.

NINGBO INNO PHARMCHEM CO.,LTD. offers a comprehensive portfolio of molecular sieve products, catering to diverse industrial needs. The range includes popular types such as 3A, 4A, 5A, 13X APG, and Carbon Molecular Sieves (CMS). Each type possesses a distinct nominal pore diameter, which dictates its specific application area by allowing only molecules smaller than its pores to be adsorbed.

Type 3A Molecular Sieve, with a pore opening of approximately 3 angstroms, is primarily used for drying unsaturated hydrocarbons, including cracked gases, olefins like propylene and butadiene, and polar liquids such as ethanol and methanol. Its structure prevents the co-adsorption of larger molecules, thus minimizing polymerization risks.

Type 4A Molecular Sieve, having a pore size of about 4 angstroms, is a versatile desiccant suitable for drying air, natural gas, and refrigerants. It is effective for removing water vapor from saturated hydrocarbons and finds application in static drying within closed systems.

Type 5A Molecular Sieve features a 5 angstrom pore diameter, enabling it to separate n-alkanes from branched-chain and cyclic hydrocarbons. It is extensively used in pressure swing adsorption (PSA) systems for producing oxygen and nitrogen, as well as for the dehydration and desulfurization of natural gas streams.

Type 13X APG Molecular Sieve is a specialized variant with a larger pore opening of around 10 angstroms. It is specifically developed for applications in the air cryo-separation industry. Its design facilitates the co-adsorption of both CO2 and H2O from air feed streams, which is crucial for preventing ice blockage and bed gelation within cryogenic units. It is known for its high adsorption capacity and faster kinetics, making it suitable for air separation plants globally.

Carbon Molecular Sieve (CMS), although distinct from zeolite molecular sieves chemically, operates on the same principle of selective adsorption based on kinetic diameter. CMS is widely used in PSA nitrogen generation systems, effectively separating nitrogen from oxygen in compressed air.

These molecular sieves are typically supplied in robust spherical or pelletized forms, optimized for performance in packed adsorption beds. Key technical specifications often considered include bulk density, crush strength, attrition resistance, and static adsorption capacities for target molecules like water and carbon dioxide. These properties ensure the longevity and efficiency of the adsorption process under varying operating conditions.
