Abstract

A composition for carbon dioxide (CO2) capture includes 2-aminocyclohexanol, cis-1,2-diaminocyclohexane, meglumine, or combinations thereof. A process of COcapture includes mixing a CO-containing gas with the composition. A system includes a component for receiving a gas and the composition, which absorbs COfrom the gas. A further composition includes a first amine solvent selected from 2-aminocyclohexanol, cis-1,2-diaminocyclohexane, and meglumine and a second amine solvent independently selected from 2-aminocyclohexanol, cis-1,2-diaminocyclohexane, meglumine, ethyl diethanolamine, dimethylethanolamine, piperidine, 2-amino-2-methyl-1-propanol, and monoethanolamine. A further process includes reacting COwith an amine selected from 2-aminocyclohexanol, cis-1,2-diaminocyclohexane, and meglumine.
