ZSM-5 and Y-zeolite as adsorbents for the adsorption of ethanol vapor were used to investigate the nonisothermal adsorption. Diffusivity and equilibrium constant in the pellet having both micro-and macropores were represented as a function of temperature to establish a nonisothermal model. More rapid adsorption rate was found in the early stage of adsorption in nonisothermal model than that in isothermal model. But the time taken to reach the equilibrium state from the start of adsorption was nearly the same for both models. As diffusivity in macropore became larger than that in micropore, the adsorption had a more rapid rate and a higher maximum temperature rise. The lower value of equilibrium constant showed a more rapid adsorption rate, but a lower maximum temperature rise. The maximum temperature rise of pellet up to 20℃ above the ambient temperature was found. When the adsorption rate curves from the experimental data are compared with those from the modeling, a deviation was obtained at a high uptake ration while a good fitting was found in the early stage of adsorption.
