“…It is found that in mixture gas separation the gas permeance is always lower compared to pure gas because of the competitive sorption between the gases 62 . After increasing the pressure up to 4 bar both CO 2 and CH 4 gas permeance decreased because of the decreases in the mobility of the polymer chain at high pressure, as a similar trend is reported in the literature 63,64 …”

“…62 After increasing the pressure up to 4 bar both CO 2 and CH 4 gas permeance decreased because of the decreases in the mobility of the polymer chain at high pressure, as a similar trend is reported in the literature. 63,64 The CO 2 /CH 4 selectivity of the APTMSH@TFN-3 membrane at variable pressure is shown in Figure 10. It is found that as pressure increases from 1 to 4 bar the selectivity becomes decreases from 26.86 to 14.41.…”

Polyamide-based thin film nanocomposite (TFN) membranes were prepared by incorporating nanoparticles in an aqueous phase containing mphenylenediamine (MPD) and an organic phase containing trimesoyl chloride (TMC) by interfacial polymerization (IP) method. The 3-aminopropyltrimethoxy silane grafted mesoporous synthetic hectorite (APTMSH) was synthesized and added in an aqueous monomer solution while the IP. In this work, the TFN layer interfacial compatibility has been enhanced by building the covalent bond between APTMSH and other two monomers by IP method. The coating of the TFN selective layer was done on the inner surface of polysulfone hollow fiber membranes. The interesting results were obtained for the binary mixture gas separation containing water vapor/N 2 and CO 2 /CH 4 . Improved gas permeance and selectivity have been obtained using APTMSH-incorporated TFN membranes. The developed TFN membranes have been characterized using several physicochemical methods. The results show that with the addition of APTMSH in MPD solution up to 0.5 w/w% the best water vapor permeance 2485 GPU and CO 2 permeance 22.3 GPU were obtained along with water vapor/N 2 selectivity 725.5 and CO 2 /CH 4 selectivity 26.
