In this study, adsorption isotherm of nitrogen and oxygen on zeolite were measured by constant volume method. The equilibrium of these gases on zeolite were well expressed by Langmuir equation, and the equilibrium constants were expressed as a function of temperature between 198K and 333K. Also breakthrough experiments were carried out on fixed bed packed with the same adsorbent. Langmuir constants were obtained by fitting experimental results to relationships between Langmuir constants, gas velocity, solute concentration, and the solute wave movement velocity based on local equilibrium theory. The equilibrium constants obtained by two different methods were compared. |
