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 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
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. Light mercaptans are also
adsorbed. It is also used for
the separation of normal- and iso paraffins. Production of high
purity N2, O2, H2 and inert gases from mixed
gas streams.

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 ******0°C is required. A properly
regenerated molecular sieve can give moisture dew points below
***0°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.
