Pervaporation of n-butanol and other fermentation broth components in ZSM-5/PDMS mixed matrix membrane |
| 초록 |
The performance of ZSM-5-filled PDMS MMMs for the pervaporation (PV) of n-butanol (n-BuOH) and other fermentation broth components was examined. Initial PV operations using n-BuOH aqueous solutions were carried out at varied feed concentrations, temperatures and ZSM-5 loadings. Increase in zeolite loading exhibited the most remarkable effect in improving the n-BuOH selectivity. The decrease in n-BuOH permeability with increased feed concentration suggests a saturation on zeolite sorption. Only zeolite loading significantly affected the water transport, which may be associated to the highly hydrophobic character of ZSM-5. Furthermore, PDMS matrix swelling was substantially controlled upon ZSM-5 addition. The MMM performance with multicomponent feed showed that the least hydrophobic ethanol was the least permeable among the organic components whereas water exhibited coupling effect with acetone.
