Comparison of ceramic α-alumina and modified γ-alumina membranes for H2 separation. (2021)
Journal Article
ORAKWE, I., ALKALI, A., SHEHU, H. and GOBINA, E. 2021. Comparison of ceramic α-alumina and modified γ-alumina membranes for H2 separation. Membrane technology [online], 2021(11), pages 8-11. Available from: https://doi.org/10.1016/S0958-2118(21)00175-0

This article provides details of a study that investigates hydrogen (H2) separation, purification and transport behaviour of a ceramic α-alumina membrane and compares it with that of a γ-alumina membrane modified with Boehmite sol.

Comparison of hydrogen transport in dense and porous ceramic membrane systems. (2021)
Presentation / Conference
GOBINA, E., SHEHU, H., ORAKWE, I. and ALKALI, A. 2021. Comparison of hydrogen transport in dense and porous ceramic membrane systems. Presented at 8th International conference and exhibition on advanced and nanomaterials 2021 (ICANM 2021), 9-11 August 2021, [virtual conference].

In this study, hydrogen permeation behaviour was investigated for both dense and porous ceramic composite membranes. Selected porous supports were tested and highly active metallic species was impregnated into the porous structure using the repeated...

Development and testing of inorganic membranes for hydrogen separation and purification in a catalytic membrane reactor. (2016)
Thesis
ALKALI, A. 2016. Development and testing of inorganic membranes for hydrogen separation and purification in a catalytic membrane reactor. Robert Gordon University, PhD thesis.

Palladium membranes have been identified as the membranes of choice in hydrogen separation and purification processes due to their infinite selectivity to hydrogen when defect-free. Despite their potentials in hydrogen processes, palladium membranes...
