Mixed matrix membranes of Matrimid 5218 loaded with zeolite 4A for pervaporation separation of water–isopropanol mixtures

ZIF‐11/Matrimid® mixed matrix membranes for efficient CO2, CH4, and H2 separations

“…Figure showed the gas separation performance of Matrimid®‐ZIF‐11 MMMs as a function of 0, 10, 20, 30, 40 wt.% ZIF‐11 loadings. The gas separation performance of the pure Matrimid® membrane obtained in this study was found to be consistent with the values reported in the literature . In the pure Matrimid® membrane, the gas permeation fluxes for H 2 , CO 2 , and CH 4 pure gases were found to be 17.33, 4.20, and 0.26 Barrer, respectively.…”

Ag-exchanged NaY zeolite introduced polyvinyl alcohol/polyacrylic acid mixed matrix membrane for pervaporation separation of water/isopropanol mixture

“…7,18,33,37 Membrane thickness of present study is 50 mm and higher ux with marginally decreased in the separation factor can be obtained by decreasing the membrane thickness according to the solution diffusion model 5 and Fick's law of diffusion. Fabrication of composite membrane by applying thin layer of AgNaZ-M5 membrane on porous support is feasible.…”

Pervaporation and membrane reactor performance of polyimide based mixed matrix membranes containing MOF HKUST-1

“…In addition, mixed matrix membranes (MMMs) using zeolites such as silicalite-1 (Moermans et al, 2000), ZSM-5 (Zhan et al, 2012) and 4A zeolite (Khosravi et al, 2012;Nigiz et al, 2012), functionalized carbon nanotubes (Qiu et al, 2010) or magnesium oxide (Jiang et al, 2007) as fillers have been studied for the dehydration of ethanol and isopropanol, achieving higher selectivities and/or fluxes than those of the pristine polymer membranes. To improve the matching between the filler and the polymer matrix, MMMs comprising mesoporous inorganic materials such as dual pore SBA-15 and silica MCM-41 Flynn et al, 2013;Kudasheva et al, 2014) have also been proposed.…”
