In the meantime, temperature profiles of bed were investigated in adsorption and decompression procedure by the adiabatic experiment and the coincidence between temperature wave and concentration wave was observed. Adiabatic experiment revealed the relation between temperature wave andconcentration wave in bed and showed that pressure swing adsorption of air separation for O2 product was a non- isothermal process. Secondly, pressure swing adsorption of air separation was calculated and analyzed based on mathematical models, which fully considered the mass-transfer, heat-transfer and momentum-transfer of non-isothermal process. The mathematical models consisted of axial dispersed plug flow models of fluid, energy balance models of gas-solid and bed wall, adsorption equilibrium model of LRC and mass transfer model of LDF, which was designed for six-step cyclic process(feed repressurization, adsorption, cocurrent depressrizing pressure equalization, counter-current depressrization or evacuation, product purge and countercurrent pressuring equalization).
