For oxygen production, lithium molecular sieves (such as LiX type) or high-performance modified zeolite molecular sieves (such as 13X, 5A type) should be preferred. This type of molecular sieve has a higher nitrogen and oxygen separation coefficient and adsorption capacity. It can efficiently separate oxygen in the air and produce oxygen-rich gas with a purity of 90%-95%. It is suitable for medical, health care and industrial scenarios.
Comparison of mainstream oxygen production molecular sieve types:
Lithium type molecular sieve (LiX type)
Advantages: The nitrogen adsorption capacity is more than twice that of traditional molecular sieves, the oxygen recovery rate is higher, the energy saving effect is significant, the service life is longer (up to more than 10 years), and it is suitable for long-term oxygen therapy needs.
Applicable scenarios: high-end household oxygen concentrators, medical grade equipment, continuous operation conditions.
Sodium type/calcium type zeolite molecular sieve (such as 13X, 5A type)
Advantages: Low cost, mature technology, widely used in small and medium-sized oxygen generating devices.
Limitations: The adsorption efficiency and oxygen purity are slightly low (usually 80%–90%), the lifespan is relatively short (5000–8000 hours), and it is suitable for intermittent use.
Composite and modified molecular sieves
Performance is improved through ion exchange or doping with elements such as lithium and magnesium, taking into account high purity and stability. It is commonly used in industrial VPSA oxygen production systems.
