Powder preparation effect on oxygen permeation flux of hollow fibre LSCF6428 ceramic perovskite membrane / Mohd Haikal Mustafa

The industrial demand for pure oxygen had increased throughout the years. It is expected the market for this commodity will massively expand in the near future. However, the current industrial normal processes to produce pure oxygen from air have their limitations. Alternatively, oxygen production t...

Based from the results obtained, it was shown that both membranes were gas tight at ambient temperature and gave relatively the same oxygen permeation flux at several temperature values. Given that both membranes successfully achieved asymmetric structure, which provide small oxygen permeation resistance and large surface area for oxygen surface reaction, it was deem that the membrane structure and configuration in the shape of hollow fibre played a significant factor in determining the oxygen permeation flux as compared to powder preparation method. In conclusion, the powder preparation method does not directly affect the oxygen permeation flux through hollow fibre membrane. 2015 Thesis NonPeerReviewed text en http://ir.uitm.edu.my/id/eprint/18384/2/TM_MOHD%20HAIKAL%20MUSTAFA%20EH%2015_5.pdf Mustafa, Mohd Haikal (2015) Powder preparation effect on oxygen permeation flux of hollow fibre LSCF6428 ceramic perovskite membrane / Mohd Haikal Mustafa.
