3a Zeolite Molecular Sieve For Biogas Drying Ethanol Drying Molecular Sieve Adsorbent
Product Description
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.
