What Are Zeolite Molecular Sieves?
Zeolite molecular sieves are crystalline structures that, on a molecular
scale, are not unlike sponges. They have a solid framework, defined
by large internal cavities where molecules can be adsorbed. These cavities
are interconnected by pore openings through which molecules can pass,
and because of their crystalline nature, the pores and cavities are
all precisely the same size. Depending on the size of the openings,
they can adsorb molecules readily, slowly, or not at all, thus functioning
as molecular sieves -- adsorbing molecules of certain sizes while rejecting
larger ones.
The ability of these molecular sieves to attract and sort molecules is also
affected by the electrical charge or polarity of the molecules being sorted.
Synthetic zeolites possess the unique ability to selectively adsorb molecules
by size and polarity. This is the key to their unusual efficiency as agents
for drying and purifying liquids and gases. Such abilities also serve as the
basis for separation.
Synthetic zeolites can be manufactured to provide a wide range of desired adsorption
characteristics or selectivities, and can be used as a separation tool for
numerous commercial applications.
Traditional molecular sieves work as desiccants, adsorbents, and ion exchangers.
UOP also offers high silica zeolites for non-traditional applications, including
the removal of organic bodies that can cause odors or affect taste within food
and beverage packaging.
