“…This work is a continuation of our previous efforts, and was mainly undertaken for improving the separating performance of the PDMS membrane for better process efficiency. Various hydrophobic zeolites had been used as filler in enhancing membrane selectivity for gaseous separation [5][6][7], and for organic species removal [8][9][10] from aqueous streams by pervaporation. For removing relatively larger organic species (e.g., higher alcohols), zeolites with larger molecular sized pores are needed.…”

Mixed matrix membranes were prepared by incorporating ZSM-5 zeolite particles into polydimethylsiloxane. A uniform dispersion of the zeolite in the membrane was obtained. The membranes were characterized with scanning electron microscopy, and the effects of zeolite loading on membrane performance were evaluated. It was found that 80 wt.% ZSM-5 loading was optimal for selectivity. Further increase in the zeolite loading either improved the selectivity slightly or even lowered the membrane selectivity while the membrane permeability was consistently reduced. The improved separating performance of the filled membranes was attributed to the filler-polymer interactions, and the mass transfer contribution of surface flow through the zeolite pores. The advantage of the improved membrane performance was demonstrated in a simulated continuous operation enriching 2,3-butanediol in a mixture with 1-butanol from 5 to 99.5 wt.% as a retentate using both the filled and un-filled PDMS membranes. Results showed that the filled PDMS membrane improved the recovery of 2,3-butanediol significantly while achieving the same product purity.Crown

“…25 With n-butane, enhancement in permeability coincided with a substantial enhancement in n-butane/CH 4 mixed gas selectivity. 25 Both n-butane permeability and n-butane/CH 4 selectivity enhancement have been attributed to increases in the FFV of PMP as FS particle loading increases. 25 Barsema et al used nanoparticles that selectively adsorb a permanent gas in an attempt to improve overall membrane selectivity.…”

Abstract.This study investigates the effect of additive rice husk silica and Polyethylene glycol (PEG) on the performance of polysulfone (PSf) membrane. The membrane was prepared by phase inversion method using PSf, N-methyl-2-pyrrolidone (NMP) and rice husk silica was added as an additive. The performance of the membrane was analyzed by using distilled water for permeation test and humic acid for rejection test. The result showed that the hydrophilic of PSf/PEG membrane has significantly improved permeation and rejection with addition of rice husk silica. The results showed that the addition of 3% rice husk silica give highest rejection flux at 196.63 L/m²hr with the rejection value 98%.
