• Pressure swing adsorption — (PSA) is a technology used to separate some gas species from a mixture of gases under pressure according to the species molecular characteristics and affinity for an adsorbent material. It operates at near ambient temperatures and so differs from …   Wikipedia

• Catalyst for pressure swing adsorption — Pressure Swing Adsorption (PSA) processes rely on the fact that under pressure gases tend to be attracted to solid surfaces, or adsorbed. The higher the pressure, the more gas is adsorbed; when the pressure is reduced, the gas is released, or… …   Wikipedia
