Abstract:
Carbon capture and utilization is currently considered one of the most interesting strategies to reduce CO2 as it involves its transformation into fuels and chemicals. In this work, tetrabutylphosphonium acetate hydrate ([P4 4 4 4][AcO]·H2O) is used as an ionic liquid additive to impregnate the pores of a polymeric polysulfone (PSf) membrane and increase the CO2 solubility and selectivity. Impregnated and non-impregnated membranes are characterized by Scanning Electron Microscope (SEM) and infrared spectroscopy (FTIR). The ionic liquid was prepared by acid-base neutralization reaction and characterized by 1H NMR. The solubility and permeability of impregnated membranes were tested from pure CO2 gas in a steel module setup.
