Presentation Transcript

    1. Yi Huang, Dan Li, Huanting Wang* Department of Chemical Engineering Monash University Clayton, VIC 3800 Australia. huanting.wang@eng.monash.edu.au Zeolite-polymer composite membranes for desalination

    2. Zeolites — Molecular sieves

    3. Zeolites: potential for desalination Pore size

    5. Synthesis of zeolite membranes In-situ and secondary growth Microwave heating synthesis Dry-gel conversion Defects: cracks, pinholes, inter-crystal gaps

    6. Ion rejection by MFI zeolite membrane

    7. Thin zeolite-polymer composite membranes

    8. Hand-cast and commercial membrane separation performance

    9. Developing zeolite-polymer membranes Zeolite nanocrystals: crystal size, size distribution, pore size (crystal structure) Interfacial compatibility and defects

    10. Synthesis of zeolite nanocrystals Controlling zeolite nucleation and growth Involving structure –directing agents (SDA) Synthesis of SDA-free zeolite nanocrystals??

    11. Confined-space synthesis Activated carbon as inert matrix Polymer hydrogels

    12. Carbon matrix in confined space synthesis Nanocrystal aggregates Infiltration of zeolite gels Crystallization outside the carbon matrix

    13. Synthesis of zeolite nanocrystals in thermoreversible polymer hydrogels

    16. Colloidal silica nanoparticles Commercially available Mondisperse silica can be readily prepared by Stober’s method. (Stober, W.; Fink, A. J. Colloid Interface Sci. 1968, 26, 62-69).

    17. Direct conversion?

    26. Advantages of our new method controlling nanocrystal size distribution via silica size distribution eliminating crystallization outside the mesoporous carbon matrix producing dispersible zeolite nanocrystals (no intercrystal growth)
