CMS - Carbon Molecular Sieve
A Carbon Molecular Sieve (CMS) is the porous carbon skeletal framework remaining after the pyrolysis of a polymeric precursor. Carbon molecular sieve is a non-polar adsorbent that fuses the ideas behind both activated carbon and zeolites into one product, with adsorbing oxygen molecule to get nitrogen-enriched air at normal temperature (Nitrogen Generation).

Carbon molecular sieve (CMS) specializes in separating oxygen from nitrogen, an important part in natural gas processing. This process is done with a PSA (Pressure Swing Adsorption) device in two phases.
The carbon molecular sieves is widely applied in petroleum chemical industry, the heat treatment of metal, the electronic manufacture and food preservation industries.
