Molecular sieves are the core adsorption material used in PSA (Pressure Swing Adsorption) oxygen generation technology.
Their unique microporous structure enables them to distinguish the adsorption rates of different gases in air.
Because molecular sieves have a much stronger affinity for nitrogen than for oxygen, oxygen can be quickly enriched, making molecular sieves an indispensable component in modern oxygen production systems.
1. Working Principle in Oxygen Production
In a PSA oxygen generator, compressed air enters an adsorption tower filled with molecular sieve.
The sieve preferentially adsorbs nitrogen, allowing oxygen to pass through more rapidly and enter the storage tank.
When the adsorbent becomes saturated, the system lowers the pressure to release nitrogen, regenerating the molecular sieve for the next cycle.
Through this rapid “adsorption–desorption” process, PSA systems are able to produce high-purity oxygen continuously and efficiently.
2. Key Application Areas
Molecular sieve oxygen technology is widely used across various industries:
● Medical oxygen concentrators: Provide stable, high-purity oxygen for home therapy, hospital systems, and emergency use.
● Industrial oxygen generators: Applied in metal processing, glass manufacturing, ozone generation, environmental treatment, and other industrial processes.
● Food processing and aquaculture: Create high-oxygen environments for storage, packaging, and cultivation, improving product quality.
● Chemical oxygen supply systems: Enhance oxidation reactions and combustion processes, increasing reaction stability and efficiency.
With advantages such as fast startup, low energy consumption, and simple maintenance, PSA oxygen generation has become a globally adopted oxygen production method.
