he trick with mole sieve is the construction. These adsorbents are
made with tiny and uniform pores, making them ideal adsorbents. In
this way,molecular sieve
desiccants work like any common sieve, only on a much more precise
level. When a gas or liquid is passed through the mole sieve,
smaller pieces are adsorbed while larger molecules pass through.
Unlike other filters, the adsorbed substance is then trapped.
Therefore, when water is used in the sieve, penetrating water
molecules are caught and retained in the pores, leaving the
remaining liquid substantially cleared of the water molecules. In
all, a mole sieve adsorbs up to *2% of its own weight in water.
More than that, these sieves are exceptionally versatile, with
adsorption possible based on molecular size, molecular affinity for
the sieve crystal surface, or even the shape of the molecule. For
these reasons, molecular sieve desiccants can produce gases or
liquids that are virtually water free. Molecular sieve can be
regenerated by heating it to an optimal temp from **0°C to
**0°C.
