“…[19][20][21][22][23][24] Because of its superior hydrophilicity, citric acid (CA) cross-linked PVA membrane has been used as a pervaporation membrane to separate water during esterification but not as a catalyst support. 22 In addition, PVA was used as a main membrane matrix to prepare poly (styrene sulfonic acid) (PSSA)/PVA membrane for catalyzing esterification although its role as a water absorber was not recognized.…”

Sulfonated cation exchange resins (s-CER) have been widely studied as a replacement of liquid acids for the catalysis of esterification of free fatty acids (FFAs) to produce biodiesel with water as the only by-product. However, the water produced has strong affinity to sulfonate groups in s-CER, which blocks the reactive sites for esterification and thus reduces the activity of the catalyst. To overcome this technical barrier, we have designed an s-CER/PVA composite by incorporating s-CER fines within a poly (vinyl alcohol) (PVA) matrix. PVA has much stronger absorption preference of water than s-CER and has very low selectivity for the reactants (FFAs and methanol), which enables the continuous removal of the produced water and liberation of reactive sulfonate sites in s-CER for catalysis. With s-CER/PVA, the FFAs conversion was increased from 80.1 % to 97.5 % after 8-hour reaction and the turnover frequency (TOF) was increased more than 3.3 times. The TOF of s-CER/PVA was also 2.6 times of that of sulfuric acid, suggesting that the water less, heterogeneous sulfonate sites are more reactive than water-blocked homogeneous ones. The reusability of the s-CER/PVA was also enhanced due to that the produced water that could cause deactivation of the s-CER was largely removed by PVA.

“…Due to the need of oil for feeding purposes and for biofuel production; alternative raw materials, pointed out in section 2, are being evaluated, tested and used. The uses of these new raw materials have generated new processes to carry on the transesterification reaction, example of this are: acid homogeneous catalyst (Marchetti et al, 2007, Srivastava & Prasad, 2000, Ma & Hanna, 1999, Fukuda et al, 2001, Knothe et al, 2005, Marchetti, 2010, Zheng et al, 2006, solid resins (Bajaj et al, 2010, Ranganathan et al, 2008, Antczak et al, 2009, Rodrigues et al, 2008, Dalla Rosa et al, 2008, Matassoli et al, 2008,supercritical alcohols (Demirbaş, 2002, 2003, Hawash et al, 2009, Gui et al, 2008, Kasim et al 2009 (Dubé et al 2007, Baroutian et al, 2011, Zhu et al, 2010, Cheng et al, 2010, monolithic catalysts (Kolaczkowski et al, 2009, Dizge et al, 2009, Tonetto & Marchetti, 2010, etc. Besides the different technologies and their applicability, we would like to introduce a few thoughts in relation to the prospective future of biodiesel production.…”

“…However, if the leaching problem is solved, the reaction will be more environmentally friendly and the Biodiesel produced will be of better quality. Membrane reactors have been widely used for the water gas shift reaction with great results (Dubé et al 2007, Baroutian et al, 2011, Zhu et al, 2010, Cheng et al, 2010. Dubé et al (Dubé et al, 2007) used them and succeeded in producing a final product of high quality.…”

“…The soap produced will also be a problem for the downstreaming separation of the biodiesel and the glycerol. The saponification reaction could be seen in Figure 2 (Marchetti et al, 2007, Srivastava & Prasad, 2000, Ma & Hanna, 1999, Fukuda et al, 2001, Knothe et al, 2005, Marchetti, 2010 In order to avoid this problem, the technological solutions put forward were: the use of homogeneous acidic catalysts such as sulfuric acid (Knothe et al, 2005, Marchetti, 2010, Schuchardt et al, 1998, Noureddini & Zhu, 1997, Freedman et al, 1984, Zheng et al, 2006, Canakci & Van Gerpen, 2003a, 2003b, solid catalysts such as zeolites, solid resins (basic as well as acid) (Bournay et al, 2005, Di Serio et al, 2005, Soriano et al, 2009, Hamad et al, 2008, Suppes et al, 2004, Kulkarni et al, 2006, López et al, 2008, enzymatic technologies (Bajaj et al, 2010, Ranganathan et al, 2008, Antczak et al, 2009, Rodrigues et al, 2008, Dalla Rosa et al, 2008, Matassoli et al, 2008, supercritical alcohols (Demirbaş, 2002, 2003, Hawash et al, 2009, Gui et al, 2008, Kasim et al 2009), membrane reactors (Dubé et al 2007, Baroutian et al, 2011, Zhu et al, 2010, Cheng et al, 2010, monolithic reactors …”

“…Although high water uptake facilitates proton conduction, an excessive water swelling leads to low mechanical strength in PEMs. To overcome the swelling problem in PVA-based membranes, the membranes are either crosslinked or incorporated with inorganic materials [8][9][10] . The development and the commercialization of perfluorosulphonic acid membranes are limited to operating temperatures below 100°C because the proton transport mechanism, namely vehicular mechanism, relies on the presence of water 11,12 .…”

Electrospun fibres from polyvinyl alcohol (PVA), poly(styrene sulphonic acid-co-maleic acid) (PSSA-MA), and imidazole for potential use as proton conducting membranes at elevated temperatures were prepared and characterized. The effect of PSSA-MA content (9,17,25,33, 42, and 50% by weight of PVA) on solution properties was investigated. Fibre mats were obtained from solutions with 9-33% PSSA-MA. Solution viscosity increased with increasing PSSA-MA until reaching a maximum at 33% PSSA-MA. The effect of PSSA-MA content on fibre size and morphology was studied using scanning electron microscopy. Fibre diameter was found to increase with increasing solution viscosity. A solution with 25% PSSA-MA provided uniform and bead-free fibres with an average diameter of 485 nm. Thermal crosslinking of electrospun fibres was confirmed by attenuated total reflection Fourier transform infrared spectroscopy and thermogravimetric analysis. Electrospun fibres were thermally stable up to 250°C. Fibres containing 25% PSSA-MA had a proton conductivity in nonhumidified conditions comparable to that of a solvent-cast membrane with the same composition. The proton conductivity of a solvent-cast membrane was slightly higher than that of fibres over the temperature range studied.
