Investigation of gas permeation behavior in facilitated transport membranes: Relationship between gas permeance and partial pressure

Permeation characteristics of hydrogen through palladium membranes in binary and ternary gas mixtures

“…Figures a and a indicate that increasing the H 2 partial pressure difference decreases the permeance. Similar behavior has been observed in other studies . This might be attributed to more hydrogen ions in the lattice at high pressure difference that makes the movement of the ions relatively difficult, thereby reducing the permeance.…”

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

“…Firstly, according to the formulas reported in the literature [31], the CO 2 flux (the CO 2 permeance multiplied by the pressure difference) increases gradually with increasing feed pressure, and the increased CO 2 molecules will occupy a part of the transport channels of H 2 , which restrains the H 2 transport in the membrane. Therefore, with increasing feed pressure, the H 2 permeance of the PVAm-MEA/PS and PVAm-DEA/PS membranes decreases continuously according to the formulas reported in the literature [31]. Secondly, the membrane compaction may also occur at high pressure, which would decrease the H 2 permeance of the PVAm-MEA/PS and PVAm-DEA/PS membranes.…”

Widening CO2-facilitated transport passageways in SPEEK matrix using polymer brushes functionalized double-shelled organic submicrocapsules for efficient gas separation

“…The CO 2 permeability in Fig. 12(a) facilitated equation as reported [27,[57][58][59], and CO 2 diffusion coefficient (D A ) and diffusion coefficient of CO 2 -carrier complex (D AC ) contributing to the total diffusion coefficient are obtained by facilitated equation (4) and calculated equation parameters are listed ( Table 2). …”
