| dc.description.abstract | The main objective of the present work is to study the CO2 separation from fossil fuel combusted power plants using CO2-selective thin-film composite dense polymeric and mixed matrix membrane containing different combinations of amine carriers and inorganic as well as hybrid fillers. The primary focus is to achieve CO2-selective membrane by facilitated transport mechanism having impressively high CO2 permeability along with high CO2/N2 selectivity at temperature and pressure values closely resembling the actual industrial flue gas conditions. Poly (vinyl alcohol) (PVA) was used as base polymeric material due to its excellent hydrophilic nature and good film-forming ability. Thermal stability of PVA has been improved by using formaldehyde (HCHO) as cross-linking agent. Poly (ethylene glycol) (PEG) was used as the polymer blend. Various combinations of amines acting as fixed and mobile carriers such as polyethyleneimine (PEI), triethylenetetramine (TETA) and piperazine glycinate (PG) were utilized to improve the CO2 transport property. Silica prepared by Stober’s process and zeolitic imidazolate framework-8 (ZIF-8) metal-organic framework (MOF) was used as filler material. The filler particles were further functionalized by amine functional groups such as 3-aminopropyltrimethoxysilane (3-APTMS) and polyethyleneimine (PEI) and utilized for gas separation studies. Different combinations of amine carriers and functionalized and unfunctionalized filler materials were introduced into the polymer hydrogel in the preparation of CO2-selective polymer and mixed matrix membranes. | en_US |
