Preparation and characterization of small molecular amine modified PVAm membranes for CO2/H2 separation

Parametric analysis and potential prediction of membrane processes for hydrogen production and pre-combustion CO 2 capture

“…Therefore, assuming that the thickness of the separation layer of the typically used membrane vibrates from 1 to 100 μm, the corresponding permeance values, such as 20, 100 and 800 GPU, were selected for calculation and discussion. Additionally, these permeances are within the range of the reported data (Kim et al, 2001;Lin et al, 2006;Qiao et al, 2015). To view the results more clearly, Fig.…”

“…Moreover, graphene oxide membranes have been reported to achieve selectivity above 3400 (Li et al, 2013). For CSM membranes, the CO 2 /H 2 selectivity that facilitates membrane transport has been reported as above 63 with a permeance of 104 GPU (Qiao et al, 2015); further improvement of the membrane material will result in higher selectivity. Therefore, the membrane selectivity boundary has been dramatically extended, and the corresponding optimum operation conditions and potential usage for hydrogen purification should be calculated and evaluated.…”

A Highly Permeable Aligned Montmorillonite Mixed‐Matrix Membrane for CO2 Separation

“…Mixed-gas separation of CO 2 with the AMT/PSf membrane compared with that of RMT/PSf and other polymeric and mixed-matrix membranes reported in the literature, tested using dry gases. [13][14][15][16][17][18][19][20][21] Ü Ü These are not the final page numbers! a much higher CO 2 /H 2 separation performance in particular (see the Supporting Information).…”

Recent developments in membranes for efficient hydrogen purification

“…In recent years, our group introduced a novel method that various amino group-containing small molecules were used to modify amino group-rich polymers via hydrogen-bonding crosslinking, which not only could achieve the optimization of membrane material structures at multiple levels, but also could increase the carrier concentration in the membranes [283][284][285][286][287]. Following this strategy, ethylenediamine (EDA), piperazine (PIP), monoethanolamine (MEA) and methylcarbamate (MC) were used as modifiers to incorporate into the PVAm matrix, and the formed hydrogen-bonding crosslinked networks were illustrated in Fig.…”

“…Following this strategy, ethylenediamine (EDA), piperazine (PIP), monoethanolamine (MEA) and methylcarbamate (MC) were used as modifiers to incorporate into the PVAm matrix, and the formed hydrogen-bonding crosslinked networks were illustrated in Fig. 27 [287]. Effects of physicochemical properties and content of small molecular amines on membrane performances were intensively studied.…”
