Diffusion of benzene in NaX zeolite, studied by thermal frequency response

Article Abstract:

The diffusion of benzene in NaX zeolite at various loadings and temperatures is studied by using a thermal frequency response technique (TFR). The results revealed that the discrepancies between the results obtained by various techniques do not depend on the macroscopic or microscopic character of the technique used.

Temperature-programmed desorption and infrared spectroscopic studies of benzene adsorption in zeolite ZSM-5

Article Abstract:

The adsorption and desorption of benzene over the zeolite H-ZSM-5 is investigated using simultaneous Fourier transform infrared (FTIR)-temperature-programmed desorption (TPD) measurements. The results confirmed the existence of Bronsted and non-Bronsted sites for the adsorption of benzene in H-ZSM-5.

Infrared evidence of a third bronsted site in mordenites

Article Abstract:

The location of protons and sodium ions in the structure of MOR is discussed. Fourier transform infrared (FTIR) spectroscopy is used for the examination of a series of progressively proton-exchanged sodium mordenite.

An investigation is conducted of the structure, stability and transformation of the P(sub n)3(sub m) bicontinuous cubic phase through synchrotron x-ray diffraction in the monoolein-water system. It appears the full hydration properties of monoolein are strongly related to the pressure.
