5A molecular sieves can adsorb any molecules smaller than this pore size and are generally called calcium molecular sieves. In addition to the functions of 3A and 4A molecular sieves, it can also adsorb C3-C4 n-alkanes, ethyl chloride, ethyl bromide, butanol, etc., and can be used in the separation of n-isoparaffins, pressure swing adsorption separation and water and co-adsorption of carbon dioxide. Based on the industrial application characteristics of 5A molecular sieves, the 5A molecular sieves we produce have high selective adsorption and fast adsorption speed. They are especially suitable for pressure swing adsorption and can be adapted to pressure swing adsorption of oxygen, hydrogen, carbon dioxide and other gases of various sizes.

Applications

Mainly used for the separation of normal isoparaffins, oxygen and nitrogen separation, drying and refining of chemicals, petroleum and natural gas, ammonia decomposition gas and other industrial gases and liquids.

1. Deep drying of gases and liquids such as air, natural gas, alkanes, and refrigerants

2. Preparation and purification of argon gas

3. Static drying of pharmaceutical packaging, electronic components and perishable substances

4. As a dehydrating agent in paints, fuels and coatings

Molecular sieve 5A has a pore size of 5 angstroms, meaning it cannot absorb molecules smaller than 5A. This type is an alkali aluminosilicate in the claim form of Type A crystal structure. That means it will separate normal and isomerous alkane, the co-absorption of moisture and carbon dioxide, as well as pressure swing absorption (PSA) for various gases.
