Abstract

The purpose of this study is to investigate the performance of amine-grafted sorbents, specifically when they are degraded at 120°C. This study varied the amine source and the amount of it in the sorbent. The additive type and the amount of it was also manipulated. The performance of sorbents is characterized by CO₂ capture capacity, which is the amount (in mmol) of CO₂ captured per gram of sorbent at 40°C. The best performing sorbents are ones that maintain their CO₂ capture capacity after degradation. When the amount of additive was manipulated, the sorbents containing 2% b.w. and 5% b.w. were the best. When the type of additive was manipulated, sorbents containing sodium carbonate and rubidium carbonate performed the best after degradation. Lastly, the amine source and amount of that source in the sorbent was manipulated. The sorbent containing 30% b.w. TEPA outperformed the other sorbents by a large amount. In summary when selecting a sorbent for carbon dioxide capture, one with an additive type of rubidium carbonate and an amount of 5% b.w. should be used. Additionally, the amine source and amount of that source should be 30% b.w. TEPA.
