Nanocellulose-based membranes for CO2 separation from biogas through the facilitated transport mechanism: a review

A highly permeable porous organic cage composite membrane for gas separation

“…However, as the feed gas pressure increased, both the CO 2 permeance and CO 2 /N 2 selectivity decreased gradually, which was consistent with the typical characteristic of a facilitated transport mechanism. 57,58 Meanwhile, the TPC-RCC3@PIP/mPSf composite membrane was also fabricated by a similar procedure with CC3 cages and PIP as the aqueous monomers. As shown in Fig.…”

Latest technological advances and insights into capture and removal of hydrogen sulfide: a critical review

“…282 In addition, membrane separation can optimize the gas separation processes by lowering the energy requirement in the presence of pressurized gas, reducing the size of equipment and capital costs and improving the process safety, and it does not require a complex system to operate. 283 Besides, H 2 S removal can be accomplished effectively via membrane separation at low cost at both offshore and remote areas. 284 Nonetheless, current research and development of membranes were focusing mainly on CO 2 removal instead of H 2 S. There was a higher emphasis on membrane development for various industrial gases such as light hydrocarbons, CO 2 , N 2, O 2 and H 2 based on review papers to date.…”

Immobilized Nanomaterials for Environmental Applications

“…For example, nanocellulose-based membranes (NCM) have extensively been employed to eliminate this GHG. NCM offer great advantages for the removal of CO 2 , such as a high specific surface area, hydrophilicity, the option to modify their surface, environmental friendliness, and outstanding mechanical properties [ 85 ]. Since the diffusion mechanism involved in the separation of CO 2 through NCM occurs very slowly, there are several challenges still to be addressed for promoting their extensive application in industrial processes.…”
