Carbon dioxide capture using a superhydrophobic ceramic hollow fibre membrane for Gas-liquid contacting process
Journal of Cleaner Production, 2017Co-Authors: Mohammed Abdulmunem Abdulhameed, Mohd Hafiz Puteh, Mohd Hafiz Dzarfan Othman, Mukhlis A Rahman, Juhana Jaafar, Zawati Harun, Ahmad Fauzi Ismail, Masoud Rezaei, Siti Khadijah HubadillahAbstract:This work initiates the development of clean technology in carbon dioxide (CO2) capture using ceramic membrane inspired by Gas–liquid contacting system. A low cost, high performance superhydrophobic kaolin-alumina hollow fibre membrane was prepared via phase inversion-based extrusion and sintering techniques, followed by a grafting with fluoroalkylsilane (FAS). The membrane was characterized by scanning electron microscopy (SEM), Gas Permeation test, contact angle, wetting resistance, X-ray photoemission spectroscopy (XPS), X-ray diffraction (XRD) and thermal gravimetric analysis (TGA). The fabricated membrane was highly porous, thus increasing the Gas Permeation Rate. By surface modification, the membrane contact angle was increased from 0° to 142°. In fact, wettability resistance of the membrane was also improved. The membrane was subsequently applied in membrane contactor for carbon dioxide (CO2) absorption. The CO2 absorption flux as high as 0.18 mol m−2 s−1 was achieved at the liquid flow Rate of 100 mL min−1 which was far above the fluxes of some commercial and in-house made polymeric and ceramic membranes. In conclusion, the modified kaolin-alumina hollow fibre membrane with the superhydrophobic surface, high permeance, and absorption flux is suitable for CO2 post-combustion capture, due to its outstanding chemical and thermal stabilities.

the role of layered silicate loadings and their dispersion states on the Gas separation performance of mixed matrix membrane
Journal of Membrane Science, 2014Co-Authors: Abdul Karim Zulhairun, Ahmad Fauzi IsmailAbstract:Abstract Mixed matrix membranes (MMMs) embodying different types of organoclays, namely Cloisite ® 5, Cloisite ® 15A and Cloisite ® 30B as the disperse phase for Gas separation membranes, were prepared. Polysulfone (PSF) has been used as host matrix to prepare asymmetric membranes attained by the dry–wet phase inversion casting process. FESEM analysis has revealed that defect-free asymmetric MMM morphology with no issues pertaining to non-ideal organic–inorganic interphase was fabricated. The effects of organoclay types and loadings on Gas Permeation properties were characterized by constant pressure and the variable volume method. From the Gas Permeation experiment, all nanocomposites exhibited significant reduction in the Gas Permeation Rate even with the addition of very low clay loadings (less than 1 wt%). The results suggested that the clay particle loading dictated the extent at which the organoclays were dispersed in the polymer matrix as well as their Gas discrimination ability. The information on the degree of clay dispersion, aspect ratio, and the number of clay stacks per tactoid unit was gleaned by making use of the famous phenomenological models derived by Nielsen and Cussler׳s group. PSF–C15A membranes with the loading of 0.05 wt% were found to be comprised of exfoliated clay nanoplatelet (confirmed by XRD and TEM analysis) with calculated aspect ratio of more than 500 giving rise to striking selectivity (CO 2 /CH 4 ideal selectivity=52.67 for PSF–C15A 0.05 ) well above the recognized intrinsic selectivity for PSF membrane.

asymmetric mixed matrix membrane incorporating organically modified clay particle for Gas separation
Chemical Engineering Journal, 2014Co-Authors: A K Zulhairun, Ahmad Fauzi Ismail, Takeshi Matsuura, Mohd Sohaimi Abdullah, Azeman MustafaAbstract:Abstract Asymmetric MMMs were fabricated containing various amount of organically modified clay particle (Cloisite® 15A) with the main intention to investigate the Gas Permeation behavior of the resultant material combination. The fabricated MMMs were characterized by X-ray diffraction (XRD), thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), field emission scanning electron microscopy (FESEM) and pure Gas Permeation testing. XRD analysis suggested that clay layers crystalline structure was slightly changed upon blending but only limited polymer chain intercalation occurred thus resulted in phase sepaRated clay–polymer composite. The Gas Permeation properties were evaluated by pure Gases: nitrogen, oxygen, methane, and carbon dioxide. The Gas Permeation Rate was observed to be increasing with increasing clay content while the selectivity remained at par to that of unfilled PSF before it declined at 2 wt.% C15A loading due to filler agglomeration as confirmed by FESEM. The best results were obtained at 1 wt.% C15A loading where more than 270% enhancement in O2 and CO2 permeance were observed, with insignificant change in O2/N2 and CO2/CH4 selectivity compared to that of neat PSF.
