Description

Molecular sieve is a material containing tiny pores of a precise and uniform size that is used as an adsorbent for gases and liquids. Molecules small enough to pass through the pores are absorbed while larger molecules are not. It is different from a common filter in that it operates on a molecular level. For instance, a water molecule may be small enough to pass through while larger molecules are not. Because of this, they often function as a desiccant. Molecular sieve can absorb water up to *2% of its own weight. We are proud to provide series of molecular sieves with strong ability of selective absorption, high mechanical strength, high abrasion resistance, and thermal stability. In accordance with your specific needs, specification of molecular sieve can be adjusted to match your application.

It does not adsorb any molecular larger than 3A. According to the industrial application specialties, our products have the characters of higher adsorption speed, stronger crushing and anti-contaminative resistance, more cyclic times and longer work-span. All these advantages have made it come to be the most essential and necessary desiccant in the fields of the deep drying, refinery polymerization for cracked gasses (pyrolysis gas), ethylene, propylene and any other non-acidic gasses of liquids in petroleum and chemical industrials. 　 Formula 0.4K2O · 0.6Na2O · Al2O3 · 2.0SiO2 · 4.5H2O 　 Typical Application Dehydration of many kinds of liquids (such as ethanol) Dehydration of air Dehydration of refrigerant Dehydration of natural gas or methane Dehydration of cracked gas (pyrolysis gas), ethylene, propylene or butadiene *******************************************************************************- 5A Molecular Sieve It&#**9;s a kind of appropriative molecular sieve specially designed for medical or healthy oxygen generator - a mini PSA plant for medical application. The product has the character of high purity of oxygen concentrating and long work-span. It is already widely used in the medical care field. 　 Formula 0.*0CaO · 0.*0Na2O · Al2O3 · 2.0SiO2 · 4.5H2O 　 Typical Application Drying, purification of air Absorption of CO2 *******************************************************************************- 　 *3X Molecular Sieve It&#**9;s a sodium form of type X crystal and has a larger pore opening than type 4A molecular sieve.
