The reaction kinetics of CO2 absorption into new carbon dioxide binding organic liquids (CO2 BOLs) was comprehensively studied to evaluate their potential for CO2 removal. A stopped-flow apparatus with conductivity detection was used to determine the CO2 absorption kinetics of novel CO2 BOLs composed of DBN (1,5-diazabicyclo[]non-5- ene)/1-propanol and TBD (1,5,7-triazabicyclo[]dec-5-ene)/1-butanol. A modified termolecular reaction mechanism for the reaction of CO2 with CO2 BOLs was used to calculate the observed pseudo-first–order rate constant k 0 (s−1) and second-order reaction rate constant k 2 (m3/). |
