| Research Abstract |
Adsorption behaviors of the isomeric mixture of 2,6- and 2,7-dimethylnaphthalene (DMN) (two-component systems and single-component systems) dissolved in supercritical carbon dioxide using NaY-type zeolite as the adsorbent were studied in order to clarify the mechanism of separation by supercritical phase adsorption. The experiments were performed at the several temperatures and pressures and the effects of temperature and pressure on the adsorption behaviors were examined. It was shown that the higher separation efficiency, the lower adsorption amounts, and the shorter breakthrough times for both 2,6-and 2,7-DMN were obtained at higher pressure or lower temperature in two-component systems. Moreover, the experimental breakthrough curves obtained for all systems were correlated by a model using mass-transfer coefficient by assuming a linear adsorption equilibrium. The model gave good correlation results for the all experimental breakthrough curves.
