Granule 8*12 Mesh 5A Molecular Sieve Bead for PSA Adsorber
Granule 8*12 mesh 5A molecular sieve bead for PSA adsorber
Product Description.
Chemxin Molecular Sieve type 5A is an alkali alumina 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 adsorption applications.

Typical Application |
a)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 mini missing COS formation. Light mercaptans are also adsorbed. b) Separation of normal- and iso paraffin's. c) Production of high purity N2, O2, H2 and inert gases from mixed gas streams d) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled. |

Warranty: |
a)By National Standard GB 13550-1992. |

2.Typical Application:
- Used for the separation of normal- and iso- paraffins (C4 to C6 species);
- Used in in PSA hydrogen purification;
- Used in in oxygen concentrators;
3. Regeneration:
Chemxin molecular sieve Type 5A can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes. To remove moisture from a 5A molecular sieve, a temperature of 250-300°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C, or mercaptans or CO2 levels below 2 ppm.The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
4. Size:
5A - Zeolite 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 1.6mm, 3.2mm.
5. Attention:
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
