Carbon Molecular Sieve (CMS) by SorbiTech Group

Carbon Molecular Sieve (CMS) is a microporous carbon adsorbent engineered for Pressure Swing Adsorption (PSA) nitrogen generation. The narrow pore structure separates nitrogen from oxygen in compressed air by kinetic selectivity, delivering high purity nitrogen continuously across long bed cycles.
SorbiTech Group supplies Carbon Molecular Sieve to PSA plant operators, industrial gas companies, and PSA system manufacturers worldwide. Each CMS batch is manufactured to ISO 9001:2015 standards with direct engineering support for grade selection, vessel sizing, and bed loading across the full lifecycle.
How CMS Drives Nitrogen Generation Inside the PSA Cycle
Carbon Molecular Sieve (CMS) is the core adsorbent in PSA nitrogen generators. It works by kinetic separation, selectively adsorbing oxygen and trace components from compressed air while allowing nitrogen to pass through as the product gas.
In a typical two tower PSA system, one vessel produces nitrogen in the adsorption step while the other regenerates by depressurization and purge. The valves switch the flow between the towers to keep nitrogen production continuous.
High quality CMS supports shorter, stable cycles and consistent purity, helping improve nitrogen recovery and reduce operating issues over long runtimes in industrial gas applications.
