The oxygen-producing adsorbents mainly relies on its selective adsorption to nitrogen and oxygen penetrating function. They’re mainly divided into calcium-based CaA and CaX, and lithium-based LiX. CaA and CaX adsorbents are based on traditional molecular sieves used in the 1980s, therefore the cost is lower, but the energy consumption of producing oxygen is higher, therefore, total lo...

In the 1970s, Union Carbide Corporation industrialized pressure swing adsorption (PSA) oxygen generation technology for the first time using normal pressure desorption (PSA) process. The adsorbent was CaA adsorbent with low nitrogen adsorption capacity and high oxygen power consumption. In the 1990s, vacuum pressure swing adsorption (VPSA) oxygen production technology using LiX...

What is pressure swing adsorption? (technical principles) /What gases can be separated by pressure swing adsorption technology？ The basic principle of Pressure Swing Adsorption (PSA) is to use the difference of the adsorption characteristics of the gas components on solid materials and the change of adsorption capacity with pressure regulations, to achieve gas separation or purification ...

1.Based on Science & Technology at the Beginning In 1988, Xie Youchang, a professor at Peking University, developed a copper-based adsorbent with high selectivity for carbon monoxide based on the principle of spontaneous monolayer dispersion in basic research. The new adsorbent won US, Canadian and Chinese patents and was rated as the best known carbon monoxide adsorbent with muc...
