Crystallographic Structure Determination of MFI-Zeolite Nanosheets
Ultrathin MFI-zeolite nanosheets can be packed on porous supports to create molecular sieve membranes. The nanosheets on porous support reduce morphological damage seen in regular MFIzeolite crystals [1]. MFI-zeolite belongs to pentasil family of zeolites where the periodic building unit (PerBU) is composed of 12 interconnected SiO4 tetrahedral (T12) units of 41m2 (D2d) symmetry [2]. Rotation 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 کاملGas Diffusion in Polycrystalline MFI-type Zeolite Membranes
1. Introduction 1. Introduction Information on mass transport in polycrystalline zeolite membranes is necessary for a theoretical estimation of the membrane performances. Zeolite membranes are usually prepared as thin layer of an assembly of small zeolite crystals including many intercrystalline regions. Thus, the intercrystal region would influence their individual diffusion properties, which ...
متن کاملPhysical adsorption analysis of intact supported MFI zeolite membranes.
We compare the adsorption properties of intact supported silicalite membranes with those of silicalite powder and of alumina supports using nitrogen and argon as adsorbates at 77 K. We disentangle contributions from the membrane and support and find that the support contributes significantly to the total quantity adsorbed due to its relative thickness. The micropore-filling regions of the adsor...
