A PEBAX-nano zeolite X mixed matrix membrane was fabricated and operationally characterized using single gas (CO۲) permeation. X-ray diffraction (XRD) analysis was used to study the arrangement of polymer chains of mixed matrix membrane. The membranes were characterized by scanning electron microscopy (SEM) to study cross-sectional morphology. The single gas permeability were carried out for neat PEBAX and PEBAX-nano zeolite X (۱۰ wt. %) membranes. Operating pressures varied from ۶ to ۱۴ bars. CO۲ permeability for the nano-composite membrane was higher than the neat polymer membrane and increased with pressure. Adding ۱۰ wt.% of nanozeolite X into the polymeric matrix caused CO۲ permeability to increase. Both structurally and operationally characterizations revealed the defect-free structure of the nano composite membrane.
