Mixed matrix membranes (MMMs), as opposed to polymer membranes, are scaled up without difficulty, provide exceptional separation concert, and have longstanding stability. However, mass production of such membrane materials is a difficult problem. To address the shortcomings of polymeric membranes, researchers have investigated microporous membranes made of zeolites, carbon molecular sieves (CMS), and metal oxide framework (MOFs)-based films. As a result, it is worthwhile to investigate. Moreover, the combination of ZIF-8 as a filler with sodium alginate was new and had not been reported previously. The NCMs did not, however, outperform a neat polymer membrane in terms of their ability to separate mixtures of gases. The purity of H 2 increased to as high as 95% among the measured values. NCMs (ZIF-8) having H 2 permeability of 28 Barrer and H 2/CH 4 selectivity of 125 outperformed neat polymer membranes in terms of separation performance at ambient temperature and 4 kg/cm 2 pressure. NCMs were prepared with a 15% filler loading, i.e., synthesized ZIF-8. ZIF-8 crystals were created through hydrothermal synthesis, with sizes varying from 50 to 70 nm. The potential of nanocomposite membranes (NCMs) prepared by the sodium alginate polymer and embedded with synthesized zeolitic imidazole framework-8 (ZIF-8) as fillers having microporous structure in the application of separation of gaseous mixture generated by the process of methane reforming was assessed.
