Abstract

The elementary steps of sorption and transport of benzene, toluene and p-/o-xylene on MFI-type zeolites were studied by fast time-resolved rapid scan IR spectroscopy. The transport into the zeolite pore proceeds via a weakly bound physisorbed state on the external surface. Due to the weak interaction, very low sticking probabilities in the order of 10^-7 for porous and non-porous materials were observed. The sticking coefficients increased in the series toluene, o-xylene, benzene, and p-xylene, attributed using to the statistical thermodynamic analysis, to the symmetry of the sorbate molecule, the sorption enthalpy of the sorbate which increases with molar mass and the space the sorbate molecule occupied on the surface.
