3a Zeolite Molecular Sieve For Biogas Drying Ethanol Drying
Molecular Sieve Adsorbent
The 3A molecular sieve adsorbent has a 3 angstrom (3A) pore size;
this means that any molecule that is larger than the 3 angstrom pores will not be adsorbed. The 3A molecular sieve, the potassium type of A crystalline
structure, is a form of alkali aluminosilicate that is created when
potassium ions partially replace the sodium ions of a 4A sieve. For
a 3A molecular sieve, the sequence rate that adsorption occurs is
He, Ne, N, and H2O.
Due to the crystalline structure, molecular sieves that have a 3 angstrom pore size have a very high rate of adsorption and properties
(including an increased resistance to outside contamination and
crushing strength stronger than other desiccants) that promote a
longer life for products treated by the sieve. The most common use
for the 3A molecular sieve is to remove water and moisture from
materials that are in gas and liquid form.
