Özet:

 

The reaction kinetics of CO22_{2} absorption into new carbon dioxide binding organic liquids (CO22_{2}BOLs) was comprehensively studied to evaluate their potential for CO22_{2} removal. A stopped-flow apparatus with conductivity detection was used to determine the CO22_{2} absorption kinetics of novel CO22_{2}BOLs composed of DBN (1,5-diazabicyclo[4.3.0]non-5-ene)/1-propanol and TBD (1,5,7-triazabicyclo[4.4.0]dec-5-ene)/1-butanol. A modified termolecular reaction mechanism for the reaction of CO22_{2} with CO22_{2}BOLs was used to calculate the observed pseudo-first-order rate constant k00_{0} (s−1)−1)^{-1}) and second-order reaction rate constant k22_{2} (m33^{3}/kmol.s). Experiments were performed by varying organic base (DBN or TBD) weight percentage in alcohol medium for a temperature range of 288-308 K. It was found that k00_{0} increased with increasing amine concentration and temperature. By comparing using two different CO22_{2}BOL systems, it was observed that the TBD/1-butanol system has faster reaction kinetics than the DBN/1-propanol system. Finally, experimental and theoretical activation   energies of these CO22_{2}BOL systems were obtained and compared. Quantum   chemical calculations using spin restricted B3LYP and MP2 methods were   utilized to reveal the structural and energetic details of the single-step   termolecular reaction mechanism.
