Clay based ceramic support was prepared by uniaxial pressing method and Titanium dioxide (TiO 2 ) and γ-Alumina (γ-Al 2 O 3 ) composite membranes were fabricated individually by coating of TiO 2 and γ-Al 2 O 3 particles on the prepared ceramic support via hydrothermal method. The prepared TiO 2 and γ-Al 2 O 3 powders as well as membranes were systematically characterized using analytical techniques such as thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), BET surface area, X-ray diffraction analysis (XRD), particle size analyzer, scanning electron microscope (SEM), porosity, field emission scanning electron microscope (FESEM), N 2 gas permeation and pure water permeability. Filtration experiments were performed to evaluate the performance of the support and membranes by separation of synthetic oil-in-water emulsions. The effects of applied pressure and feed (oil) concentration on the treatment of oil-in-water emulsion for the support and membranes were examined. TiO 2 membrane demonstrates better rejection (97-99 %) and permeate flux (8.48-55.13×10 -5 m 3 /m 2 s) as compared to the support (rejection of 95-97 % and permeate flux of 1.87-9.84×10 -5 m 3 /m 2 s). Also the γ-Al 2 O 3 membrane shows good rejection (96-98 %) and permeate flux (6.12-22.03×10 -5 m 3 /m 2 s). Despite similar rejection shown by the support and composite membranes, the flux of the TiO 2 membrane is one order higher than that of the support due to the enhanced hydrophilic character of the membrane after TiO 2 coating.Hence, the prepared composite membranes can be used as potential candidates for the treatment of oil-in-water emulsions.

A B S T R A C TThe objective of this study was to prepare low-cost macroporous ceramic membranes using natural kaolin and natural lignite, as porogen agent, both from Tunisia. The characteristics of this membrane have been defined to be used in filtration processes and as a support for multilayer ceramic membranes. This study includes the characterization of the raw materials in order to define optimal processing parameters to obtain the membranes. A study of the effect of lignite content has been carried out. Porosity, density and mechanical strength were the considered parameters to be optimized. A lignite percentage of 20% and a sintering temperature of 1,050˚C were chosen. Obtained membranes show good porosity above 43% but with a slightly low mechanical strength that does not exceed 20 MPa. These membranes can be considered as efficient regarding the results shown in the gas permeation tests.

High‐temperature CO₂ removal from CH₄ using silica membrane: experimental and neural network modeling

Inorganic membranes can operate under harsh conditions. However, successful synthesis of inorganic membranes is still challenging, and its performance depends on many factors. This work reports the effect of dip‐coating duration, inlet pressure, and inlet flow rate on the flux, permeability, and selectivity of silica membranes. A silica membrane was prepared by the deposition of silica sol onto porous alumina support. The permeability test was conducted at 100 °C using a single gas of CO2 and CH4. The highest flux was observed at the maximum inlet pressure and inlet flow rate for the membrane prepared at the minimum dip‐coating duration. The neural network modeling of the membrane predicted permeabilities showed a considerably high validity regression (R ≈ 0.99) of the predicted data linked to the experimental sets. The separation factor (α) was the highest at the maximum dip‐coating duration. The synthesized silica membrane has potential for CO2/CH4 separation under harsh operating conditions. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.
