4A can mainly used to adsorb water, methanol, ethanol, sulfureted hydrogen, carbon oxide, ethylene, propylene.

The pore size for 4A molecular sieve is 4A. It can mainly used to adsorb water, methanol, ethanol, sulfureted hydrogen, carbon oxide, ethylene, propylene, does not adsorb any larger molecular than 4A, and often used as desiccant in industries.
