“…2 In the past few decades, attempts have been made to upgrade the NG, including liquid absorption, solid adsorption, cryogenic distillation, and membrane separation. 3 Up to now, the organic amine-based liquid absorption is the most widely used technology for NG gas sweetening, 4 while the membrane technology has been considered as a promising alternative to conventional separation technologies due to its intrinsic advantages including small footprints and no moving parts, thus easy maintenance, and most importantly, there is no phase change in the membrane gas separation processes, thus leading to high theoretical separation efficiency. 5 Membranes have been extensively studied for NG-related separations.…”

Membranes have been considered as promising alternatives for natural gas sweetening. Mixed matrix membranes (MMMs) possess superior gas separation performance and the potential to combine varieties of polymers and filler materials. In the current work, MMMs have been fabricated via employing Troger's base (TB) polymer and zeolites with three different morphologies. Simultaneously, CO 2 /CH 4 and H 2 /CH 4 separation performances of the obtained MMMs were comprehensively investigated. It is found out that the presence of the MFI-type zeolites significantly improved the gas permeability, but the selectivity was somehow reduced. Among the three different nanofillers, nanosheet zeolite-based MMMs presented the highest gas permeability; with 20 wt % nanosheet zeolites, both CO 2 and H 2 permeabilities were increased to 348.6 and 441.5 Barrer, which were improved by 522.0 and 256.2%, respectively. In addition, SEM, XRD, FTIR, and TGA were also employed to characterize the obtained MMMs.
