文摘
- •
A dual system, consisting of [bmim][Tf2N] and DBU in 1-hexanol medium has been developed for CO2 capture.
- •
Intrinsic reaction rate of this system -measured by a stopped flow technique- follows termolecular reaction mechanism.
- •
The developed solvent has a high CO2 loading capacity and favorable reaction kinetics.
- •
Activation energy of the reaction between the dual system and CO2 was found to be 55.62 kJ/mol.
- •
FITR studies showed that the loaded solvent can be regenerated at 363 K without a reboiler requirement.
