The proposed project will investigate and assess the capabilities of amino acid salts (AAS) for carbon dioxide capture. Many amines have been investigated for their carbon dioxide absorption and desorption characteristics. Among them, the monoethanolamine (MEA) is considered the benchmark due to its absorption kinetics and good carbon dioxide uptake rate. However, the corrosivity and toxicity of MEA can impose significant challenges on the operational personnel and the equipment. In addition, MEA's material performance will degrade over time and will reduce the carbon dioxide absorption efficiency. Amino acid is a green material group due to its low toxicity, negligible volatility, and excellent absorption capacity. Amino acid salt solutions can be readily prepared by the reaction of an amino acid with alkaline substances.
