Zeolite 5A Molecular Sieve for Pressure swing absorption
Detailed Product Description
Molecular Sieve 5A is an alkali alumino silicate; it is the calcium form 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
0.7 CaO . 0.3 Na2O . Al2O3 . 2 SiO2 . 4.5H2O
SiO2 : Al2O3 ≈2
Application
1) The strong ionic forces of the divalent calcium ion makes it an excellent adsorbent to remove water, CO2, H2S from sour natural gas streams, while minimising COS formation.
2) Light mercaptans are also adsorbed.
3) It is also used for the separation of normal- and iso paraffins.
4) Production of high purity N2, O2, H2 and inert gases from mixed gas streams.

Regeneration condition of molecular sieve:
Temperature at the entrance of absorption tower is 250-320 oC; temperature at the exit≥150 oC;
Gas for regeneration must be dry and excluding contents which can be absorbed by molecular sieve. (suggested gas: dry nitrogen);
Time of regeneration: 3~4 hrs at stable temperature;
Usually, regeneration gas is used to cool down the base.
Size
5A - Zeolites are available in beads of 1-2 mm, (10x18 mesh) 2-3 mm, (8x12 mesh) , 2.5-5 mm, (4x8 mesh) and as powder, and in pellet 1.6, 3.2.
