      abstract     = {This work reports the preparation and investigation of
                      novel mixed matrix carbon stainless steel (MMCSS) membranes.
                      The study involves the production of MMCSS hollow fibres
                      using SS particles of 6, 10, 16 and 45 μm in diameter,
                      polyetherimide as a polymeric binder and pyrolysis using a
                      N2 inert atmosphere. As a result, the binder pyrolysed to
                      carbon was retained in the hollow fibre structure, filling
                      the voids between the SS particles. Smaller SS particles (6
                      μm) yielded a bi-modal pore size distribution and superior
                      mechanical properties. An interesting morphological feature
                      was the formation of honeycomb-like carbon structures
                      between the SS particles, attributed to the densification of
                      the hollow fibre during pyrolysis at 1050 °C. The MMCSS
                      hollow fibres (6 μm) delivered almost pure N2 for the
                      separation of a synthetic flue gas composition $(13\%$ CO2
                      and $87\%$ N2). It was found that CO2 had a strong affinity
                      to the surface of the MMCSS materials (isosteric heat of
                      adsorption of 38 kJ mol−1) whilst N2 was a non-absorbing
                      gas. Therefore, CO2 permeation was controlled by surface
                      diffusion whilst N2 was controlled by the faster Knudsen
                      diffusion mechanism. For CO2 feed concentrations in excess
                      of $13\%,$ the CO2 diffusion increased as the excess CO2
                      could not adsorb on the fully saturated surface of the MMCSS
                      hollow fibres, thus slightly reducing the N2 purity in the
                      permeate stream.},
