Molecular Sieve 4A

Molecular Sieve 4A

Molecular Sieve 4A is an alkali metal aluminosilicate; Molecular sieve 4A is the sodium form of the type A crystal structure. Molecular sieve 4A adsorbs molecules with effective diameters small than 4 angstrom (0.4nm) such as water, Co2, H2S, Methanol, etc. 

Product Description

Molecular Sieve 4A is made from zeolite powder 4A (>70%) and binder. Zeolite powder 4A is generated by reaction of water, sodium hydroxide, sodium silicate and sodium aluminate. Molecular sieve 4A is usually used for in packaging of drugs, electronic components. Since 4A molecular sieve is easier to be produced than 3A molecular sieve, 5A molecular sieve, 13X molecular sieve, it is more economic than other three desiccant. Molecular Sieve 4A have the shape of beads, pallets.

More Details:

1. Typical Chemical Formula: Na2O.Al2O3.2SiO2.4,5H2O

2. Silica-alumina ratio: SiO2/ Al2O3б≈2

Application:

1. Molecular sieve 4A can be used for drying and removing of Co2 from natural gas, LPG, air, etc.

2. Molecular sieve 4A can be used for removal of hydrocarbons, ammonia and methanol from gas streams (ammonia syn gas treating)

3. Molecular sieve 4A can be used in dehydration of refrigerant and air in the air brake units of buses, trucks and locomotives

4. Molecular sieve 4A can be packed in small bags for packing desiccant for foods, electronics elements, drugs etc
