4A molecularsieve is sodium A type silica aluminate. 4A molecular Sieve can absorb molecules of critical diameter less than 4A.
About Molecular Sieves 4A
4A molecularsieve is sodium A type silica aluminate. The molecular Sieve can absorb molecules that have a diameter of 4A or less. It can adsorb water, methanol, hydrogen sulfide, carbon dioxide, sulfur dioxide, ethylene, propylene, etc. Any molecules which can be adsorbed with the 3A molecular sieve can also be adsorbed using the 4A type.
