Abstract Details

2015, Master of Science, University of Akron, Polymer Science.
The impurities in flue gas from coal fire power plant such as SO2, could poison CO2 sorbent due to its strong acidity. To reinforce the stability of sorbent in presence of SO2, polymeric SO2-resistant coating was developed and characterized by in-situ FTIR spectroscopy. This coating was prepared by crosslinking poly(ethylenemine) with an epoxy and applied to CQA-12, a solid amine sorbent. The effect of the epoxy composition on the stability and adsorption / desorption kinetics of the coated sorbent was investigated by FTIR and mass spectrometry. The results revealed that this polymeric coating enhanced the resistance to SO2 poisoning, thus the multi-cyclic stability of the sorbent in presence of SO2, by converting the amine sites to secondary and tertiary amine. Though it reduced the initial CO2 capture capacity due to blocked amine sites. Increased amount of epoxy was found to strengthen the SO2 resistance. The FTIR spectra denoted that the introduction of epoxy increased the ratio of weakly adsorbed CO2 to strongly adsorbed CO2, i.e., reduced the binding strength of amine/CO2.
