ABSTRACT
Adsorption thermodynamics of n-butane and n-heptane on 5A zeolite was studied by the flow gravimetric-chromatograph technique at temperatures ranging from 533 K to 653 Kand over a range of hydrocarbon partial pressures. It is shown that the equilibrium amount of n-heptane adsorbed is much larger than that of n-butane. Adsorption isotherms are modeled satisfactorily by using a modified virial equation and the Dubinin—Astakhov (D—A) equation.It is concluded that the influence of n-butane is very small while the influence of n-heptane is significant in the separation stage of the total isomerization process.
