Introduction:
Molecular Sieve 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
(1) 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.
(2) Light mercaptans are also adsorbed.
(3)Â It is also used for the separation of normal- and iso
paraffins.
(4)Â Production of high purity N2, O2, H2 and inert gases from
mixed gas streams.

Regeneration
XINTAO 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.
Size
5A - Zeolites are available in beads of **2 mm, (*0x*8 mesh)
**3 mm, (8x*2 mesh) , 2.**5 mm, (4x8 mesh)Â and as powder, and
in pellet 1.6, 3.2.
Attention
To avoid damp and pre-adsorption of organic before running, or must
to be reactivated
