H4EDTA-and SiCI4-vapor-dealuminated zeolite Y were realuminated with aqueous solutions of NaAIO2 and NaOH. The products were characterized by using XRD, MAS n.m.r., F-/3.r., and second-derivative F'/].r. techniques. The results clearly show that insertion of aluminum species into the frameworks of t

Palladium-iridium catalysts with different proportions between the metals and supported on a dealuminated Y zeolite (SAR $ 26) had their activity and selectivity measured in tetralin hydrogenation at 523 K and 4 MPa. Characterization of the zeolite support showed that it was free from extra-framewor

The location of sodium and calcium cations in zeolite A has been studied using far-IR spectroscopy. Spectroscopic measurements show a shift in the vibrational spectra with the partial replacement of Na+ by Ca'+ cations in the zeolite matrix. The magnitude of these shifts is observed to be dependent
