The equilibrium and dynamics of low concentrations of benzene, toluene, and
xylene in heptane adsorbed by zeolite NaY at 30, 40, and 50 degrees C were
studied. The Langmuir equation was suggested to simulate the isotherms. Ba
sed on isotherms and material balances, multi-component competitive adsorpt
ion isotherms can be successfully predicted by mono-component adsorption is
otherm parameters. A series of column adsorption experiments were conducted
to study the adsorption dynamics. The mass transfer equations were solved
by numerical analysis and used to describe the breakthrough curves, and the
mass transfer coefficients in the adsorption column were obtained as well.
