Abstract
An aqueous solvent composition useful for COcapture is described, that includes one or more CO-sorbing amines, e.g., an amino acid salt and a tertiary or a sterically hindered amine. The solvent composition may include one or more promoters that are effective to enhance solvent characteristics such as (i) COsorption capacity, (ii) COsorption rate, (iii) COdesorption capacity, (iv) COdesorption rate, and (v) regeneration temperature, in relation to a corresponding solvent lacking the promoters. In relation to existing COcapture solvent compositions, the disclosed aqueous solvent composition provides high solvent COcapacity, high rate of COabsorption and desorption, high thermal and oxidative stability, low solvent regeneration energy, low solvent emissions, and low solvent toxicity.
