NINGBO INNO PHARMCHEM CO.,LTD. is pleased to highlight the significant capabilities of Molecular Sieve 4A, a key product in its range of chemical raw materials. As a cubic aluminosilicate compound, Molecular Sieve 4A possesses a highly uniform microporous structure, characterized by precisely sized pores. This unique structure allows it to function as a highly effective adsorbent.

Molecular sieves, including the 4A type, are distinguished by their ability to preferentially adsorb molecules based on size and polarity. The uniform pore size of Molecular Sieve 4A is approximately 4 angstroms, which means it can effectively adsorb molecules with kinetic diameters smaller than this pore size, while excluding larger molecules. This selective adsorption capability makes it an invaluable tool for separation and purification processes across numerous industries.

The adsorption mechanism of Molecular Sieve 4A is particularly effective for polar molecules and those with a small molecular weight, such as water, methanol, ethanol, hydrogen sulfide (H2S), sulfur dioxide (SO2), and carbon dioxide (CO2). It also demonstrates strong adsorption for unsaturated molecules like ethylene and propylene. This makes Molecular Sieve 4A widely applicable in various drying and purification applications, including the drying of liquids, air, and refrigerants, as well as the removal of impurities from natural gas streams.

Beyond its primary use in drying, Molecular Sieve 4A is employed in areas requiring the selective removal of specific components from gas or liquid mixtures. Its high adsorption capacity and strong thermal stability contribute to its longevity and efficiency in demanding industrial environments.

Proper handling and storage are crucial to maintain the integrity and performance of Molecular Sieve 4A. It is recommended to store the product in a dry warehouse and avoid generating dusty conditions during handling. Open packages should be carefully resealed to prevent contamination and premature adsorption of moisture or other substances from the air. Materials stored in bag-in-box packaging should ideally be used within 12 months, while those in bag-in-steel drums have a recommended shelf life of up to 24 months under proper conditions.

Regeneration is a vital process for extending the service life of Molecular Sieve 4A. After it has become saturated with adsorbed substances, its adsorption capacity can be largely restored through regeneration. Two primary methods are commonly employed: temperature variation and variable pressure. Temperature variation typically involves heating the sieve to around 200°C with a preheated purge gas to drive off adsorbates. Variable pressure swing adsorption (PSA) processes, often used in gas phase applications, involve reducing pressure and using an inert purge gas at a constant temperature to remove the adsorbed components.

Molecular Sieve 4A is typically available in granular or spherical form, packaged in various sizes such as 25kg bags or drums, and larger 150kg drums, depending on customer requirements and transport logistics. NINGBO INNO PHARMCHEM CO.,LTD., as a reliable supplier and manufacturer of chemical raw materials, ensures that its Molecular Sieve 4A meets stringent quality specifications for various industrial applications.
