The use of an aminosilicone solvent mix for the CO2 capture is described for the first time. To maintain a liquid state, a hydroxyether co-solvent is employed, enhancing physisorption of CO2. Regeneration of the capture solvent system is demonstrated over 6 cycles and absorption isotherms indicate a 25-50 % increase in dynamic CO2 capacity over 30 % MEA. In addition, a proof-of-concept for continuous CO2 absorption is verified.
