A novel SA‐f‐MWCNTs/PAN composite membrane, sodium alginate‐ functionalized multi‐walled carbon nanotubes/polyacrylonitrile, was prepared to enhance the esterification conversion rate with a pervaporation membrane reactor. The SA‐f‐MWCNTs/PAN membrane was investigated by Fourier transform infrared spectroscopy, X‐ray photoelectron spectroscopy, and scanning electron microscope. The hydrophilicity, mechanical properties, and separation performance of the composite membrane have been significantly improved. The flux of the composite membrane was 4374 g·m−2·h−1, and the separation factor was 1249 (the water content in the feed was 10 wt%, at 75°C). The composite membrane the trade‐off effect between flux and separation factor. The acid conversion rate of SA‐f‐MWCNTs/PAN membrane was up to 98.3% in 5 h at 75°C, which was a great increase of 18.3% compared with the equilibrium conversion rate of the batch reactor. In addition, SA‐f‐MWCNTs/PAN membrane exhibited good swelling resistance and reusability. The conversion rate of acetic acid was stable above 95.0% after 8 repetitive tests.

“…Introduction of POSS into a polysiloxane pervaporation membrane allows a simultaneous increase in the selectivity by a factor of 2.2 and in the permeability by a factor of 3.8, compared to the initial PDMS membrane [92]. Zhu et al [144] note that, in butanol production in a pervaporation membrane bioreactor, introduction of fluorinated fragments into the material of polysiloxane membranes considerably reduces their plugging and enhances the stability of transport properties. The development of such membranes will allow passing to commercial implementation of the integrated fermentation-pervaporation process.…”

High-Selectivity Polysiloxane Membranes for Gases and Liquids Separation (A Review)

The most promising approaches to making polysiloxane-based membranes more selective are considered. These approaches can be subdivided into three groups: (1) development of new membrane materials by copolymerization, (2) modification of the polysiloxane chain (in the backbone and pendant chains), and (3) development of mixed matrix membranes. All the three approaches are subjected to a critical analysis, and conclusions are made on the prospects for the development of high-selectivity materials and high-performance membranes based on them. The data are presented from the viewpoint of applied aspects of polysiloxane-based membranes.

“…In-situ butanol recovery during the fermentation process is a technicallysuccessful but economically-and energetically-questionable option. Different butanol separation operations especially adsorption (Yang et al, 1994), liquidliquid extraction (Teke and Pott, 2020), pervaporation (Azimi et al, 2019;Li et al, 2020;Zhu et al, 2020), and gas stripping (Xue et al, 2013a), were evaluated for butanol recovery. In a comparative study on in-situ butanol recovery technologies, Groot et al (1992) found the pervaporation and liquidliquid extraction more promising.…”

Butanol is a key microbial product that provides a route from renewable carbohydrate resources to a "drop-in" liquid biofuel, broadening its market in the near future. The acceptable performance of butanol as a neat or a blended fuel in different engines both from the technical and environmental points of view has attracted a wide range of research for reviving the old acetone-butanol-ethanol (ABE) fermentation. In this review, recent findings on fuel characteristics of butanol, different generations of substrate for large scale butanol production, and alternative process designs for upstream, mainstream, and downstream operations have been critically reviewed and discussed. In the upstream, studies devoted to designing and optimization of pretreatments based on prerequisites of butanol production, e.g., maximizing cellulose and hemicellulose recovery and minimizing lignin degradation, are presented. In the mainstream, different microbial systems and process integrations developed for facilitating ABE production (e.g., in-situ butanol removal) are scrutinized. Finally, innovations in ABE recovery and purification as "Achilles Heel" of butanol production processes which directly controls the energy return on investment (EROI), are reviewed and discussed.
