| Abstract: | the adsorption kinetics of nitrogen and oxygen on CMS and 13X molecular sieve are studied with tbe data recorded by the data Collection system of the two vessel volumetric method; The temperature swing in the adsorptio, column is discussed when nitrogen and oxygen are adsorbed or desorbed The effect on adsorption and diffusion behavior by temperature swing is discussed too, the effect of temperature depehdenee of diffusivity can not be ignored when a diffusion model is established. The data could be used in a diffusion model under nonlinear isotherm Conditions was acquired. |
