Oxygen molecular sieve adsorbent is divided into sodium molecular sieve and lithium molecular sieve, mainly used in medical oxygen production and industrial oxygen production. Psa oxygen generating technology is in recent decades developed a kind of air separation oxygen producing process, compared with the conventional cryogenic air separation oxygen generating device, psa oxygen generating device has the advantages of low investment, low energy consumption, low operation maintenance cost, mild process condition, simple process, high degree of automation, high operating flexibility, short construction period and safety, etc. It is very important to choose suitable molecular sieve for oxygen production by psa.
