Development of alumina supported ternary mixed matrix membranes for separation of H2/light-alkane mixtures

▸ PES/SAPO-34/HMA mixed matrix membrane was prepared on alumina disks. ▸ The composite membrane successfully separated H2/CnH2n+2 mixtures. ▸ The composite membrane was stable despite its intricate morphology. ▸ CO2 and CH4 adsorption capacities of PES/SAPO-34 and PES/SAPO-34/HMA were measured.
