NMR spectroscopy applied to amine–CO2–H2O systems relevant for post-combustion CO2 capture: A review

Carbon dioxide uptake as ammonia and amine carbamates and their efficient conversion into urea and 1,3-disubstituted ureas

“…The latter is due to the carbon atom of the fast exchanging À ÀCO 2 À /À ÀCO 2 H pair and the signal at 160.13 ppm should be ascribed to HCO 3 À species [55,58] The absorption efficiency of the amines was measured with the 15% CO 2 mixture in air and the cyclic absorption-filtration device (Fig. 1) which allowed the carbonated slurry to be continuously transferred from the absorber to the filtration unit and the filtered liquid to be reclaimed to the absorber.…”

The N 2 O analogy in the CO 2 capture context: Literature review and thermodynamic modelling considerations

“…Perinu et al (2014) reviewed the use of NMR spectroscopy in amine-CO 2 -water systems and showed that it is possible for the technique to achieve accuracies with errors less than 1%. Jakobsen et al (2005) reports average mass balance errors of 3.8 at 20 1C and 8.8% at 40 1C for alkanolamines.…”

An investigation of the role of N-methyl-diethanolamine in non-aqueous solution for CO2 capture process using 13C NMR spectroscopy

“…13 C NMR spectroscopy 13 C NMR spectroscopic analysis is an efficient tool which can be used to identify and evaluate the amount of different carboncontaining species during a chemical reaction (Hook, 1997;Barzagli et al, 2009Barzagli et al, , 2010Ciftja et al, 2013a,b;García-Abuín et al, 2013;Perinu et al, 2014).…”
