Abstract
MFI zeolite membranes are attractive for the separation of industrially important hydrocarbon gas mixtures such as xylene isomers, butane isomers and natural gas components, based on the differences in the chemical and physical properties. However, zeolite membranes including MFI membranes have been unsuccessful in achieving economic viability for industrial-scale gas separation applications. The large-scale industrial application of zeolite membrane systems can be realized by overcoming the following barriers: firstly, develop scalable and reliable membrane fabrication strategies to produce the high-performance membrane; secondly, reduce the cost and achieve performance intensification of the membrane system by employing hollow fiber modules with high membrane area per unit volume; and thirdly, obtain a thorough understanding of multicomponent separation behavior in zeolite membranes at industrially interesting conditions. In the above context, the overall focus of this thesis is to develop novel, technologically scalable fabrication strategies to make thin and highly selective MFI zeolite membranes and to understand their synthesis-structure-permeation property relations by a combination of experiment and modeling. This thesis has focused on the MFI zeolite type, because of its particularly attractive properties for a wide range of hydrocarbon separations.
