Product Description :

Molecular Sieve type 5A is an alkali alumino silicate; it is the calcium forms of the Type A crystal structure. Type 5A has an effective pore opening of 5 angstroms (0.5 nm). It will adsorb molecules with a kinetic diameter of less than 5 Angstrom and exclude those larger.
It is especially suitable for PSA adsorber applications where it may be used for the separation of normal- and iso- paraffins (C4 to C6 species), in PSA hydrogen purification and in oxygen concentrators.

Typical Chemical Formula :

Ca4.5 Na3 [(ALO2)12(SiO2)12] •XH2O

Application :

Molecular Sieve 5A is generally used for multiple adsorption and refinement and can be applied for liquefied and gaseous materials on the whole. Main adsorbing target are carbon dioxide and sulfuretted hydrogen including water and it can adsorb all the material whose molecular diameter is less than 5A.
The main uses are as follows:
Normal paraffin separating process

• Oxygen/hydrogen PSA (Pressure Swing Adsorption) process
• Ethanol refinement (moisture, CO2, etc.)
• Refining SF6 refrigerant for power (removing moisture and hydrocarbon)
• Separating of aromatics, H2 purification
• Liquefied petroleum gas sweetening
