变压吸附法Pressure Swing Adsorption 利用吸附剂对不同气体在吸附量、吸附速度、吸附推动力乖方面

的差异以及吸附剂的吸附容量随压力的变化而变化的特性，在加压时完成混合气体的吸附分离，降压时完成吸附剂的再生。The adsorption and separation of mixed gas and the regeneration of adsorbent are completed when pressurized by the difference of adsorbent in adsorption capacity, adsorption speed and adsorption driving force.
