The recent development of membrane in reverse osmosis has been extensively explored by the effective separation. However, reverse osmosis membranes for organic solvent separation require further development. Thus, the development of hydrophobic zeolite membranes, such as MFI membranes, for organic solvent separation is very important. By considering the optimum conditions in preparing the membranes, MFI membranes were used to elucidate their organic solvent (methanol/toluene mixture) separation performances in this study.
The synthesis conditions that can affect the MFI membrane performances are substrate, seed crystal size, synthesis time, and silica/alumina ratio. After determining these optimum conditions, high methanol flux and separation factor can be achieved in the reverse osmosis and pervaporation system.
Hydrophobic MFI membranes have a great potential in organic solvent separation in order to promote sustainability in the petrochemical, pharmaceutical, and agrochemical industries.
