Molecular Sieves are popularly known as desiccants. These Sieves are used as catalyst and also as filters. The
most popularly used Molecular Sieves are Activated Charcoal and Silica Gel. The
size of these pores is as small as one angstrom which is equivalent to one nano
meter. Molecular sieves are very popular liquid and gaseous filters which help
in easy adsorption of gases and liquids. These are made up of crystalline
alumino silicates having a three dimensional molecular network which helps in
trapping the liquid and gaseous molecules. In gas phase processes a molecular
sieve size of about 4 to 8 mesh size is usually used where as in liquid phase
application a sieve of about 8 to 12 mesh size is usually used.
Petroleum
industry is one of the highest consumers of molecular sieves to separate gasoline from the impurities. You would find molecular sieves in all chemical
laboratories where it is used as a catalyst to fasten up the chemical process.
Even fire fighters make use of this under FDA approval. Molecular sieves are
the boon for manufacturing and chemical industries for its adsorption
properties also used in water filters. These adsorbers could be used in various
different purposes. These moleculars come in different sizes depending on use.
You get 3 Angstrom and 4 Angstrom sizes which are quiet popular. These sieves
have the property of demineralizing the water which makes it fit to be used for
drinking purposes. These Sieves work on calcium ion exchange methodology and is
now used in all water filters. Off late, these sieves have found utility in
organic synthetic procedures too.
These molecular
sieves are often stored at room temperature with a
constant relative humidity of about 90 percent. These are prevented to come in
direct contact with air, water, acid and base. Other measures required to store
these adsorbents include storing in cardboard barrels. These Molecular Sieves
have an amazing drying capacity even at 90 degree celcius. Molecular sieves
have found many commercial uses and it has replaced long time taking chemical
processes to finish in just a few seconds. These microporous sieves are also
referred to as synthetic zeolites as well. These zeolites also offer different
adsorption capacities based upon their molecular shapes and the affinity
towards the substance to be adsorbed.
