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.
Claims2
An ionic liquid catalyst for catalytic CO2 capture, the ionic liquid catalyst comprising:
- a catalytic amine configured to capture CO2;
- an ionic liquid;
- wherein the ionic liquid reacts with the catalytic amine to produce an ionic liquid catalyst;
- wherein the ionic liquid catalyst is selected from the group of [EMmim+][NTF2−] based catalysts;
- wherein the ionic liquid catalyst is configured to capture CO2.
