This study focuses on the use of composite alumina membranes for the separation of carbon dioxide from methane. The technique can be applied to pre, post and oxy-combustion operations in industry and would be particularly useful in mitigating the effect of greenhouse gases in our world today. The porous tubular ceramic supports used in this study were tailor made by Ceramiques Techniques et Industrielles (CTI SA) in France consisting of an alumina support and separation layer of pore sizes ranging from 15-6000nm. The membrane layers are fixed on the support, starting with very coarse (intermediate) layers then more layers with decreasing pore sizes are added until the designated pore sizes are reached. For example, to achieve a membrane with the pore size of 6000nm, the support will have one layer (1) of a macroporous membrane, while a membrane with pore size of 200nm will have the support plus layer (1) and layer (2). Again, to achieve a membrane with mesoporous size of 15 nm, we will have the support plus layers (1 + 2 + 3). The layers are made from different materials such as aluminium oxide (Al2O3), titanium oxide (TiO2), zirconium oxide (ZrO2), silicon dioxide (SiO2), silicon carbide (SiC). Materials are carefully selected so that they are thermally compatible with the support to prevent delamination or crack formation at elevated temperatures.
