Molecular Sieve 5a For Production of High Purity N2, O2, H2 and Inert Gases
1. Introduction
Molecular Sieve type 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 isoparaffin (C4 to C6 species), in PSA hydrogen purification and in oxygen
concentrators.
2. Typical Chemical Formula
0.7 CaO . 0.3 Na2O . Al2O3 . 2 SiO2 . 4.5H2O
SiO2 : Al2O3 ≈2
3. Application
The strong ionic forces of the divalent calcium ion make it an
excellent adsorbent to remove water, CO2, H2S from sour natural gas
streams while minimizing COS formation. Light mercaptans are also
adsorbed.
It is also used for the separation of normal- and isoparaffins.
Production of high purity N2, O2, H2 and inert gases from mixed gas
streams.

5. Regeneration
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 mercaptan or CO2 levels
below 2 ppmv.
The outlet concentrations on a pressure swing process will depend
on the gas present, and on the conditions of the process.
Attention:
1. The product cannot be exposed in the open air and should be
stored in dry condition with the air-proof package.
2. The product should be regenerated after a certain period of
adsorption. The appropriate regenerated temperature would be better
below 350°C.
Packaging:
1, 25KG/carton; 2, 35KG/carton drum; 3, 150KG/Sealed iron drum
Delivery Time:
About 3-15 days after the payment.
