The pore size of 4A molecular sieve is 4A. It adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, and propylene, but does not adsorb any molecules with a diameter greater than 4A (including propane). Its selective adsorption performance for water is higher than any other molecule. It is one of the most widely used molecular sieve varieties in industry.
