Abstract: |
|
Dehydration of organics in harsh conditions is highly demanded in industrials. Although the pervaporation dehydration of bio-ethanol using NaA zeolite membrane has been industrialized, the dehydration of organics in strong acidic conditions is only at the early-stage in international membrane community, facing key issues being the poor acid resistance and flow flux of the membrane. In the present review the international research advances in development of zeolite membranes for the dehydration of organic mixtures in acidic conditions were summarized. Especially our attempts and achievements in developments of high performance MOR and ZSM-5 zeolite membranes by novel approaches of functional defects repair and micro-structural optimization respectively for pervpaoration dehydration of acetic acid were shown. The future outlook of zeolite membrane for liquid molecular mixtures is also given |
