Gas 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 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 کاملPermeation and Separation Characteristics of Mfi Type Zeolite Membranes on Zirconia Intermediate Layer by Template-free Secondary Growth Method
MFI type zeolite membranes were synthesized on two types of supporting materials, alumina (α-alumina) and yttria-stabilized zirconia (YSZ) coated alumina. Membranes were prepared by template-free secondary growth method with multiple growth steps in order to minimize intercrystalline gaps. Gas permeation characteristics, thermal and hydrothermal stability for MFI type zeolite membranes were exa...
متن کاملMolecular sieving MFI-type zeolite membranes for pervaporation separation of xylene isomers.
Molecular sieving MFI-type zeolite membranes were prepared by a secondary growth method without using an organic template. Silicalite membranes with intercrystalline pores minimized or eliminated were obtained by this synthesis method which avoids the template removal step. The silicalite membrane exhibits molecular sieving characteristics with pervaporation separation factor for p-xylene to o-...
