Preparation of PEBAX/MgO nanocomposite membrane for separation of CO2 from H2

In this work, separation of CO2 from H2 with Poly (ether block Amide)[PEBA1657] neat ad nanocomposite membranes was investigated. Basic MgO nanoparticles were employed to enhance solubility of acidic CO2 molecules into the prepared nanocomposite membranes, and then increase CO2/H2 selectivity. Separation performance of the prepared nanocomposite membranes was examined by measuring permeation of pure gases, CO2 and H2 at 25 °C and 2 bar, and the obtained results showed that presence of the nanoparticles has improved CO2 permeability and ideal selectivity of the prepared membranes, considerably
