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
Six NH4Na-Y zeolite samples were treated hydrothermally under deep-bed conditions. Aluminium released from the crystal lattice during the treatment was removed by extraction with 0.1 N HCI; this extraction also removed Na + cations. To obtain information on changes in the porous structure caused by
