- W3022421000 abstract "Membrane reactor is an apparatus that takes benefits integration of chemical reaction and membrane-based separation in the same physical device. Thus, the membrane acts as separator and also reaction vessel where the reaction occurs. Integration of continuous ethanol fermentation and membrane separation by pervaporation using an ethanol permselective polydimethylsiloxane membrane was performed. A laboratory-scale membrane bioreactor (MBR) was designed and fabricated that is applicable for design of a large-scale MBR. The performance of MBR with dilution rates of 0.04–0.24 h−1 was compared to conventional fermentation under similar geometrical and physicochemical conditions. For ethanol fermentation, in fresh medium glucose concentration of 100 g l−1 and Saccharomyces cerevisiae as biocatalysts were used. Optimum dilution rate of 0.14 h−1 was obtained based on maximum ethanol productivity. Maximum specific cell growth rate was found 0.27 h−1. The pervaporated ethanol concentrations were approximately six to seven times higher than ethanol concentration in conventional fermentation.Integration of continuous ethanol fermentation and membrane separation by pervaporation using an ethanol permselective polydimethylsiloxane (PDMS) membrane was performed. A laboratory-scale membrane bioreactor (MBR) was designed and fabricated that is applicable for design of a large-scale MBR. The performance of MBR with dilution rates of 0.04–0.24 h−1 was compared to conventional fermentation under similar geometrical and physicochemical conditions. For ethanol fermentation, fresh medium glucose concentration of 100 g l−1 and Saccharomyces cerevisiae as biocatalysts were used. Optimum dilution rate of 0.14 h−1 was obtained based on maximum ethanol productivity. Maximum specific cell growth rate was found to be 0.27 h−1. The ethanol productivity has increased at least by 22% over conventional continuous fermentation. Furthermore, pervaporated ethanol concentrations were approximately six to seven times higher than ethanol concentration in conventional fermentation. However, at very high dilution rate, the performance of membrane permeation system was quite similar to conventional fermentation; this was due to insufficient incubation time. At optimum dilution rate, experiments were performed at very high substrate concentration of 135–230 g l−1. Maximum ethanol yield was devoted to substrate concentration of 170 g l−1. Compared to conventional continuous fermentation, MBR had great advantages in terms of elimination of substrate and product inhibitions; MBR can handle high substrate concentration, with high cell density and high ethanol productivity.Sol–gel is one of the most useful techniques for preparation of inorganic membranes with fine pores in the nanometer range (1–5 nm). The sol is a stable suspension of colloidal solid particles within soft uniform solution. The gel was obtained by hydrolysis with open reflux in 24 h at 85–90 °C. The advantage of sol–gel technology is the ability to produce highly pure γ-alumina and zirconia membranes at medium temperatures of about 700 °C with uniform pore size distribution in a thin film. However, the major disadvantage of this process is that the membrane is sensitive to heat treatment, resulting in cracking on the film layer. Successful crack-free products were produced, but they needed special care and time for suitable heat curing. Only γ-alumina membranes have the disadvantage of poor chemical and thermal stability. There was no opportunity to carry heat treatment at very high temperatures above 700 °C, where at 900 °C it was expected the transformation of γ-aluminum from γ → θ → α-alumina may take place. Successful coating on supported membrane products was obtained using ZrO2. Suitable supported and unsupported zirconia-alumina membranes were developed and fabricated using the sol–gel technique. More than one hundred samples of successful and unsuccessful membranes for demonstration were fabricated. The successful results are presented and discussed. In this project, the porous ceramic supports and the metal-oxide-coated membranes were fabricated in the research laboratory at the Universiti Sains Malaysia." @default.
