Molecular Sieve
Derived from sodium potassium or calcium
alumina silicate, molecular sieve contains a network of
uniform pores and empty cavities. Molecular sieve is
non-toxic, insoluble to water and most organic solvent,
and is used as selective absorbent (organic and
inorganic), premium catalytic promoter, and premium ion
exchanger. It is the most aggressive and expensive of
primary desiccants, for demanding and unique
applications. | |

REGENERATION:
Moisture Removal: baked
under 390-660oF, 4-7 psi, dry air
continuously for 3-4 hours, and then under cool dry air
for another 2-3 hours until desiccants are completely
cooled down.
Organic Matter
Removal: baked under hot steam air for 2-3 hours
to replace organic matters with hot steam, and then
conduct the procedure to remove moisture. |

Size Selective
Adsorption:
Molecular sieve has a very porous structure consisting of
cavities and channels of uniform size (3, 4, 5, or 10 Angstroms). These
cavities and channels catch the molecules of size equal to or less than
the size of cavities and channels, and repels the molecules of the size
larger.
High Efficient Adsorbent
Due to multi-cavities and
channels existing in molecular sieves, adsorption potential of molecular
sieves is greatly enhanced. Molecular sieves are premium adsorbent applied
in low concentration and at high temperature.-
Catalyst
Cavities and unique pore
matrices structure, with good distribution of metal molecules on pore
surface, provide catalytic cracking capacity as a type of
catalyst in refinery industry.
Cation Exchange
Molecular sieves are often
used in cation exchange application. However, the molecular sieves, after
catching cations, will slight change their catalytic and selective
adsorption property. Such characteristics is used in some unique
applications. |
