The property of hydrogen separation from CO2 mixture using Pd-based membranes for carbon capture and storage (CCS)

► CO2 capture was investigated in a Pd-based bench-scale membrane. ► CO2 capture tests were carried out using the 40%CO2 + 60%H2 mixture. ► The module could enrich 40% CO2 at a feed flow rate of 0.48 N m3 h−1 up to 93%.
