The present research investigated the utilizing of single and dual-layer flat sheet mixed-matrix membranes (MMMs) for carbon dioxide (CO2) separation. In this research, zeolite 4A is incorporated into a processable polymeric material, polyethersulfone (PES) of MMMs to get the high selectivity and permeability of membrane. Single-layer flat sheet MMMs have been successfully fabricated by adjusting the weight percent of zeolite loading in total solid as the effect of zeolite loading on the performance of MMMs were investigated. It shows that the higher the zeolite loadings, the higher the CO2/CH4 selectivity which is from 1.54 at 0wt % zeolite loading to 3.20 at 20wt % zeolite loading. Besides that, dual-layer flat sheet MMMs was also successfully fabricated with blending of PES and zeolite as selective top-layer and neat PES as sub-layer. Comparison of the results of permeability and selectivity between single and dual layer MMMs with same zeolite loading were studied. The performance of these newly developed dual-layer flat sheet of MMMs gives the best result with CO2/CH4 selectivity for dual layer MMMs is 9.63, tripled of the selectivity of single layer MMMs, 3.20.

The membranes’ role is of supreme importance in the separation of compounds under different phases of matter. The topic addressed here is based on the use of membranes on the gases separation, specifically the advantages of mixed-matrix membranes (MMMs) when using carbon nanotubes as fillers to separate carbon dioxide (CO2) from other carrier gas. MMMs consist of a polymer support with additive fillers to improve their efficiency by increasing both selectivity and permeability. The most promising fillers in the MMM development are nanostructured molecules. Due to the good prospects of carbon nanotubes (CNTs) as MMM fillers, this article aims to concentrate the advances and developments of CNT–MMM to separate gases, such as CO2. The influence of functionalized CNT or mixtures of CNT with additional materials such as zeolites, hydrogel and, graphene sheets on membranes performance is highlighted in the present work.

Since the second industrial revolution, the use of fossil fuels has been powering the advance of human society. However, the surge in carbon dioxide (CO2) emissions has raised unsettling concerns about global warming and its consequences. Membrane separation technologies have emerged as one of the major carbon reduction approaches because they are less energy-intensive and more environmentally friendly compared to other separation techniques. Compared to pure polymeric membranes, mixed matrix membranes (MMMs) that encompass both a polymeric matrix and molecular sieving fillers have received tremendous attention, as they have the potential to combine the advantages of both polymers and molecular sieves, while cancelling out each other’s drawbacks. In this review, we will discuss recent advances in the development of MMMs for CO2 separation. We will discuss general mechanisms of CO2 separation in an MMM, and then compare the performances of MMMs that are based on zeolite, MOF, metal oxide nanoparticles and nanocarbons, with an emphasis on the materials’ preparation methods and their chemistries. As the field is advancing fast, we will particularly focus on examples from the last 5 years, in order to provide the most up-to-date overview in this area.
