BACKGROUND: The pervaporation separation method is considered to be a promising technique for biobutanol recovery from fermentation broths. In this work, activated carbon nanoparticles were embedded in polydimethylsiloxane (PDMS) membranes to improve the pervaporation performance. RESULTS: Adding 6 wt% nano-additives in PDMS membranes increased the flux and separation factor by 42.6% and 51.9%, respectively, compared with neat membranes at 37 ∘ C. Enhanced performance is due to: 1 the presence of additional sorption sites within the membrane with a high affinity for butanol; and 2 the porous structure of the nanofillers generate new pathways for facilitated mass transport through the membrane. The effect of the operating temperature and particle concentration on membrane performance was investigated. Membrane performance improved with an increase in the operating temperature. Higher temperature resulted in increased free volume in the PDMS chains leading to higher diffusion of butanol. Mechanical tensile tests showed that nanocomposite membranes have better mechanical stability in comparison with neat PDMS membranes with the best performance observed at 6 wt% of the nano-additives. CONCLUSION:The presence of activated carbon nanoparticles in the matrix of PDMS membranes leading to higher flux and separation factor can be beneficial for pervaporation separation of butanol from fermentation broths.

“…Membranes, which have been used for pervaporation separation of butanol, are either zeolite membranes such as silicalite zeolite membranes and ultrathin zeolite X films [55][56][57][58] or polymeric membranes. Different kinds of polymers have been reported in the literature for butanol separation such as styrene butadiene rubber (SBR) [59], ethylene propylene diene rubber (EPDM) [60], polytetrafluoroethylene (PTFE) [61], polypropylene (PP) [62], polyurethane (polyether based) (PUR) [63], polyether block-amide (PEBA) [64], poly (vinylidinedifluoride) (PVDF) [65], poly (methoxy siloxane) (PMS) [66], poly (dimethylsiloxane) (PDMS) [19], poly (1-(trimethylsilyl)-1-propyne) (PTMSP) [67] and polyamide-imide (PAI) containing cyclodextrin (CD) [68]. Polymeric membranes are less expensive and more flexible in comparison to zeolite membranes [46,69].…”

Pervaporation is a suitable technique for butanol recovery from aqueous solutions especially ABE fermentation broths. The performance of the membrane, in terms of permeation flux and modelling of the mass transfer through membranes provides a deeper understanding, which may assist to orient the research and the development of pervaporation processes. Modelling of the mass transport through the membrane is based on sorption and diffusion of the components into and across the membrane. In this study, an overview of the different models used for the pervaporation separation of butanol is presented. Up to now, the solutiondiffusion based models were the main methods used and the Maxwell-Stefan theory was very limited. In addition, to our knowledge, the pore-flow model was not applied for the modelling of butanol pervaporation separation. Moreover, the Maxwell-Stefan theory seems to be the most accurate mass transfer model to be used for the pervaporation separation method in comparison to the other models.

“…Typically, the fate of aroma compounds during the successive stages of beer manufacturing and aging is studied by determining concentrations in the liquid phase rather than in the gas phase. A number of reports have described instrumentation capable of conducting these analyses on-line, in real time, for example by coupling a gas membrane to a gas chromatograph [2][3][4] or a mass spectrometer, [5][6][7] or using a tailored liquid sampling device. 8 Most of the time however, they are performed off-line by gas chromatography (GC) aer sample preparation using techniques such as liquidliquid extraction, [9][10][11][12][13] purge-and-trap concentration, 14,15 solidphase microextraction, 16,17 stir-bar sorptive extraction, 18,19 headspace sampling, 17,20,21 or steam distillation.…”
