Molecular Sieves

Molecular Sieve Adsorption

A molecular sieve is a crystalline, microporous adsorbent, Most often a zeolite with precisely uniform pores (e.g., 3Å, 4Å, 5Å, 10Å) that removes specific molecules like water to ppm levels by size exclusion and polarity, then regenerates with heat or vacuum.

Molecular Sieve Desiccant for Gas Drying and Purification

Molecular Sieve Desiccant

Molecular Sieve desiccant is a crystalline aluminosilicate adsorbent often referred to as a zeolite, with uniform pores that selectively trap smaller molecules while blocking larger ones. This unique property makes it essential in various industries for gas separation, drying, purification, and catalysis. Because of its exceptional selectivity, it efficiently separates gases and removes moisture from industrial processes.

Molecular sieves are engineered adsorbents, typically zeolites with angstrom scale pores that separate molecules by size, shape, and polarity. They dry gases and liquids to ultra low moisture, purify process streams, and enable PSA separations. Common grades include Molecular Sieve 3A , Molecular Sieve 4A, Molecular Sieve 5A, and Molecular Sieve 13X (bulk drying, CO₂, H₂S).
