5A molecular sieve‌ is a chemical substance with a molecular formula of 3/4CaO·1/4Na2O·Al2O3·2SiO2·9/2H2O and an effective pore size of about 5Å (1Å=0.1 nanometer), or about 0.48~0.57nm‌. 5A molecular sieve belongs to alkali metal aluminosilicate with A-type crystal structure, with a specific pore size and adsorption capacity, and can adsorb any molecule with a diameter smaller than its pore size‌.

Main parameter：

Diameter(mesh): 8*12 ;  4*8

Static adsorbed water(≥ %wt): 21;  21   

Adsorption of normal ethane)(≥ mg/g):120;  120      

Bulk density(≥ g/ml): 0.65;  0.64         

Compressive strength(≥ N): 30 ;  75

Abrasion ratio(≤ %wt): 0.1;  0.1

Residual moisture content(≤ %wt): 1.5;  1.5

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.
