“…In addition, mixed matrix membranes (MMMs) using zeolites such as silicalite-1 (Moermans et al, 2000), ZSM-5 (Zhan et al, 2012) and 4A zeolite (Khosravi et al, 2012;Nigiz et al, 2012), functionalized carbon nanotubes (Qiu et al, 2010) or magnesium oxide (Jiang et al, 2007) as fillers have been studied for the dehydration of ethanol and isopropanol, achieving higher selectivities and/or fluxes than those of the pristine polymer membranes. To improve the matching between the filler and the polymer matrix, MMMs comprising mesoporous inorganic materials such as dual pore SBA-15 and silica MCM-41 Flynn et al, 2013;Kudasheva et al, 2014) have also been proposed.…”

“…Membrane permeability enhanced with temperature due to the increasing chain mobility and free spacing of the polymeric material [50][51][52] . Moreover, the diffusion rates and the vapor pressure of component increased, and the driving force between the sides of the membrane increased with temperature 53 .…”

In this study, Rhizomucor miehei lipase-coated alginate membrane was prepared and put in a biocatalytic membrane reactor to produce ethyl lactate from ethyl alcohol and lactic acid. Effects of the amount of coated lipase, reaction temperature and initial molar ratio on lactic acid conversion were investigated to evaluate the performance of the system. In order to compare the performance of the membrane reactor, the reaction was also carried out in a classical batch reactor by using lipase-immobilized membrane as a catalyst. The highest lactic acid conversion achieved was 0.63 in the membrane reactor at 50 °C, while the lactic acid conversion was 0.37 in the batch reactor under the same operating conditions. After six reaction runs, approximately 90 % of the lipase's catalytic activity was preserved in the membrane reactor.

“…The latter materials have multiple advantages compared with other inorganic materials, as reported in Table 1 . Their well-established molecular sieving and high hydrothermal stability (depending on their Si/Al ratios) make zeolites potential candidates in PV separations, depending on the zeolite structure with superior separation efficiency over polymeric membranes [ 1 , 17 ]. Thanks to these promising features, NaA zeolite membranes have been the only membranes to be commercialized and proposed for large-scale purposes [ 18 , 19 , 20 ].…”

Thanks to their well-defined molecular sieving and stability, zeolites have been proposed in selective membrane separations, such as gas separation and pervaporation. For instance, the incorporation of zeolites into polymer phases to generate composite (or mixed matrix) membranes revealed important advances in pervaporation. Therefore, the goal of this review is to compile and elucidate the latest advances (over the last 2-3 years) of zeolite applications in pervaporation membranes either combining zeolites or polymers. Here, particular emphasis has been focused on relevant insights and findings in using zeolites in pervaporative azeotropic separations and specific aided applications, together with novel concepts of membranes. A brief background of the pervaporation process is also given. According to the findings of this review, we provide future perspectives and recommendations for new researchers in the field.
