Mixed matrix membranes based on carbon stainless steel (MMCSS) hollow fibres.
Polymeric binder pyrolised forming honeycomb-like structure between SS particles.
Best mechanical and structural hollow fibres made with smaller SS 6 μm particle.
Strong CO2 adsorption (38 kJ mol−1) leading to slow surface diffusion.
High purity N2 in the permeate for the separation of flue gas (13% CO2 and 87% N2).
