摘要
A statistical thermodynamic treatment of the adsorption of methanol and ethanol in zeolite NaZSM5 at 303 K is presented that reproduces well the adsorption isotherm and differential heat of adsorption data published by M. M. Dubinin, G. U. Rakhmatkariev, and A. A. Isirikyan (Izv. Akad. Nauk SSSR, Ser. Khim. 1989, 11, 2636). The pore filling proceeds via the formation of monomeric up to tetrameric alcohol/cation complexes located in the channel intersections. The equilibrium concentrations of these s-meric complexes (s = 1-4) as a function of the overall loading as well as the potential energies and energies of formation of the complexes are determined.
