DESICCANTS AT YOUR REQUIREMENT

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.

Note: n/p = Newton per bead.

REGENERATION:
Moisture Removal: baked under 390-660^oF, 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.
