抄録

The adsorption equilibrium loadings of benzene on Toyo Calgon’s BPL activated carbon in the presence of supercritical carbon dioxide were measured by time integration of the breakthrough curves at temperatures of 313.2 and 333.2 K and pressures from 0.99 to 11.87MPa. The benzene loadings were observed to decrease with increasing pressure, even at low pressures far below the critical point, implying the effect of carbon dioxide adsorption over the amount of adsorbed benzene and solvent power of carbon dioxide. The equilibrium data were correlated by the Dubinin-Astakhov equation. Inclusion of pressure dependence in two parameters was found to be necessary in order to apply the pure component Dubinin-Astakhov equation to the studied system.
