  • Product Description
  • Technical Specification

Molecular Sieve 5A is made from zeolite powder 5A (>70%) and binder. Molecular sieve 5A is usually used for separation of the normal and isomerous alkane, co-adsorption of carbon dioxide and moisture, along with pressure swing adsorption (PSA) for gases. Molecular Sieve 5A have the shape of beads, pallets.

 

More Detailed:

Synonym: Zeolite 5A, Molsive 5A, 5A molecular sieve, 5 angstrom sieve

Typical Chemical Formula: Ca4,5 [(Al02)12(SiO2)12].nH2O

CAS NO.: 1318-02-1

Silica-alumina ratio: SiO2/ Al2O3≈2


Application:

1. Molecular sieve 5A is an excellent adsorbent to remove water, CO2, H2S from sour natural gas streams, while decreasing COS formation

2. Molecular sieve 5A can adsorb light mercaptans

2. Molecular sieve 5A also use for the separation of normal- and iso-paraffins

3. Molecular sieve 5A can use for high purity N2, O2, H2 and inert gases from mixed gas streams


Stroage:

Keep 5A Molecular Sieve in an air tight container until ready for use to avoid unintended moisture adsorption.


Regeneration&Activation:

Molecular sieve 5A can be regenerated or activated either thermal regeneration method(Thermal Swing Adsorption, TSA); To remove moisture from a 5A molecular sieve, a temperature of 200-230℃ (390-570℃)is required. Molecular sieve 5A can also be regnerated or activated by lowering the pressure in the case of pressure swing processes (PSA). A properly regenerated or activated molecular sieve can give moisture dew points below -100℃. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
