Ethanol-Water Separation Using Membrane Technology

Impact of the Si/Al ratio on the ethanol/water coadsorption on MFI zeolites revealed using original quantitative IR approaches

“…This agrees with the results stating that ethanol highly interacts with the silanol groups of the MFI zeolites in the membrane. 57,58…”

“…This agrees with the results stating that ethanol highly interacts with the silanol groups of the MFI zeolites in the membrane. 57,58 To elucidate the role of BASs on the adsorption sites of ethanol on MFI zeolites, ethanol is adsorbed on MFI-45 previously treated with lutidine, a basic probe molecule wellknown to poison the BASs of the zeolites, specifically. 59,60 The spectra of MFI-45 before and after lutidine adsorption (Fig.…”
