Formula: Na2O, Al2O3·2.0SiO2·4.5H2O
  
  The pore size for 4A molecular sieve is 4A. It is mainly used to adsorb water, methanol, ethanol, sulfureted hydrogen, carbon dioxide, ethylene, propylene, does not adsorb any larger molecular than 4A, and often used as desiccant in industrials.
Regeneration: it can be regenerated through the course of improving the temperature. Regeneration temperature is 180-350°C, and regeration time is 3-6 hours.
