4*8 Mesh Beads Molecular Seive 5A Sphere for PSA Hydrogen Purification
4*8 mesh beads molecular seive 5A sphere for PSA hydrogen purification
Product Description.
Chemxin5A molecular sieves also named Calcium molecular sieves can absorb all kinds of molecular whose critical diameter not more than itself aperture.Besides the capacity of 3A 4A molecular sieves,5A zeolite molecular sieves can adsorb C3-C4 n-alkanes,chloroethane,bromoethane,butanol,etc.

2.Typical Application:
- Desiccate, desulfuration and decarbonation for nature gas;
- Nitrogen-oxygen separation,nitrogen-hydrogen separation to make oxygen,nitrogen,hydrogen;
- Petroleum dewaxing,separate normal alkane from branched-chain hydrocarbon and cyclic hydrocarbon;
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.
