Abstract
A transformational energy efficient technology using ionic liquid (IL) to couple with monoethanolamine (MEA) for catalytic CO2 capture is disclosed. [EMmim+][NTF2−] based catalysts are rationally synthesized and used for CO2 capture with MEA. A catalytic CO2 capture mechanism is disclosed according to experimental and computational studies on the [EMmim+][NTF2−] for the reversible CO2 sorption and desorption.
Claims5
A method for catalyzing both CO2 sorption and desorption in chemisorption;
- comprising:
- providing an ionic liquid catalyst, wherein the ionic liquid catalyst is configured to capture CO2 and the ionic liquid catalyst is produced from a reaction between a catalytic amine and an ionic liquid, wherein an ester group of the ionic liquid reacts with the catalytic amine to produce the ionic catalyst;
- providing CO2 through a gas inlet;
- and
- absorbing and desorbing the CO2.
