Abstract
The adsorption separation of the isomeric dimethylnaphthalene (DMN) mi xture of 2,6- and 2,7-DMN in supercritical carbon dioxide was performe d. The experiment was carried out by using various zeolites as the ads orbent at the temperature 308.2 K and the pressures 12.0, 14.8, and 19 .8 MPa. It was found that a suitable zeolite exists for the separation of the DMN mixture and that the zeolite can adsorb 2,7-DMN selectivel y. It shows the possibility for the adsorption separation of the DMN m ixture in supercritical carbon dioxide.
