Abstract Details

2014, Master of Science, University of Akron, Polymer Science.
Porous polyvinyl alcohol (PVA) and silica particles with amine surface functional groups have been prepared for the efficient CO2 capture power plants. The porous PVA membranes or particles were obtained by phase inversion in non-solvent, using glutaraldehyde (GA) as a crosslinking agent. An insoluble amine-PVA or amine-silica network was prepared by immobilizing polyethyleneimine (PEI) on the PVA or silica surface. The performance of the amine functionalized PVA and silica sorbents were tested by CO2 adsorption, and the effect of operational parameters were determined by in-situ IR spectroscopy. The adsorption isotherms for the CO2 adsorbed species formed on amine functionalized silica sorbents were generated at different temperatures. The CO2 adsorbed species were identified by IR spectroscopy and their formation was evaluated at the typical temperature and concentration of CO2 in the flue gas of natural gas-fired power plants. Multiple data points were generated in the low partial pressure region of the isotherms to assess the equilibrium and specify the technical requirements for the sorbents to serve in CO2 capture processes for natural gas-fired power plants.
