carbon dioxide%absorption rate and capacity%1,8-diamino-p-menthane%2-amino-2-methyl-l-propanol
Aqueous 1,8-diamino-p-menthane (KIER-C3) and commercially available amine solutions were tested for CO2 absorption.A 2-amino2-methyl-l-propanol (AMP) solution with an addition of KIER-C3 showed 9.3% and 31.6% higher absorption rate for CO2 than the AMP solution with an addition of monoethanolamine (MEA) and ammonia (NH3),respectively.The reaction rate constant for CO2 absorption by the AMP/KIER-C3 solution was determined by the following equation:k2,AMP/C3 =7.702× 106 exp (-2248.03/T).A CO2loading ratio of the AMP/KIER-C3 solution was also 2 and 3.4-times highcr than that of the AMP/NH3 solution and the AMP/MEA solution,respectively.Based on the experimental results,KIER-C3 may be used as an excellent additive to increase CO2 absorption capability of AMP.
