Grazing incidence x-ray diffraction analysis of zeolite NaA membranes on porous alumina tubes.
Zeolite NaA-type membranes hydrothermally synthesized on porous alumina tubes, for dehydration process, were characterized by grazing incidence 2 theta scan X-ray diffraction analysis (GIXRD). The fine structure of the membrane was studied fractionally for surface layer and for materials embedded in the porous alumina tube. The thickness of the surface layer on the porous alumina tube in the me...
متن کاملCarbon-Zeolite NaA Composite Membranes
Zeolites are crystalline microporous materials with well-defined and uniform pore structure that find extensive industrial uses as adsorbents, catalysts and ion exchangers [1-2]. Zeolite films supported on different materials have been successfully prepared and have potential applications as highly selective membrane separators, membrane reactors, chemical sensor and microdevices [3-10]. Most o...
متن کاملTubular MFI Zeolite Membranes Made by In-Situ Crystallization
Polycrystalline MFI zeolite membranes were prepared on α-alumina tubular support by hydrothermal treatments at 413 K. The synthesized zeolite membranes were characterized by XRD, SEM and single gas permeation. The influence of hydrothermal treatment steps and the calcination time on the zeolite layer formation were investigated. MFI zeolite membrane prepared by four subsequent hydrothermal ...
متن کاملEvaluation of the dehydration performance of zeolite NaA membrane on porous alumina tube by the alumina X-ray diffraction intensity.
A zeolite NaA (A-type zeolite of ca. 0.4 nm pore size; Linde Type A, LTA) membrane for the dehydration of alcohol was characterized by X-ray diffraction analysis (XRD). Also, the relationship between the X-ray absorption and the EtOH/H2O pervaporation (PV) dehydration performance (water selectivity and permeation flux) of the LTA membrane was first investigated. The LTA membranes used here were...
متن کاملAnalysis of Elastic constants and Lattice Parameters of Fe2B from X-Ray Diffraction Technique
Elastic constants like Bulk modulus, Shear modulus and magnetic moment were calculated theoretically using the Birch–Murnaghan equations of state fitted into the equation of state. This data was compared with the experimental data Published by Chen B, Penwell D, Nguyen J H and Kruger M B 2004 Solid State Commun. The experimental data used for comparison was studied by using Energy dispersive X-...
