“…20 This value for the activation energy is close to literature data for other systems, even though our value is slightly higher than the previously commented systems. So, based on previous studies, 20 this result can be attributed to certain steric impediment for carbon dioxideglucosamine reaction.…”

Chemical reaction kinetics of carbon dioxide with aqueous solutions of D (+) glucosamine hydrochloride (2‐amino‐2‐deoxy‐D‐glucose hydrochloride) has been studied using a stirred tank reactor with a planar interfacial area. The operational variables considered in this work have been the glucosamine concentration and the reaction temperature. Specific absorption rates have been obtained and different correlations have been employed to estimate physicochemical properties of carbon dioxide in glucosamine aqueous solutions. Results indicate that the absorption process occurs in a moderately fast reaction regime with a first‐order kinetic for amine and carbon dioxide. The reaction rate constant was calculated and correlated as a function of temperature. © 2007 American Institute of Chemical Engineers AIChE J, 2008

“…A typical plot at T ¼ 303 K is shown in Figure 2; as expected, the reaction exhibits first-order kinetics for CO 2 concentration. A comparison with k 2 values reported in previous works [11][12][13][14][15][16][17][18]20,39] is shown in Table 2. Again, the CO 2 pressure applied was approximately 10 kPa.…”

The sterically hindered amines 2-amino-2-methyl-1-propanol (AMP) and 2-piperidineethanol (PE) are promising candidate absorbents for CO 2 capture. Although reaction kinetics of the CO 2 -AMP system is extensively studied, there exists some deviations in the reported kinetic parameters and there is some uncertainty about the reaction mechanism. Contrarily, kinetic data on the CO 2 -PE reaction system is scarce. In this work, these reaction systems were revisited to set right the discrepancy of previous works and facilitate and deepen fundamental understanding of these reaction systems. Kinetic data were obtained experimentally at 298, 303, and 308 K by using a stirred-cell reactor. The molarities of AMP and PE in the aqueous solutions were varied from 1 to 3 M and 0.05 to 0.25 M. Second order rate constants for the reactions with AMP and PE were equal to 809 and 899 m 3 /(kmol s) at 303 K. The increase in temperature and amine concentration caused the expected increase in the values of the observed pseudo-first order reaction rate constants. Finally, it was found that the investigated reactions were accelerated by the addition of two sterically hindered secondary amines comprising an alkyl group, viz., N-methyl-and N-ethyl-monoethanolamine, even at low additive concentrations (0.05-0.1 M).

“…Saha and Bandyopadhyay [9], Xu et al [10], and Camacho et al [11] studied the reaction rate constants for the reaction between CO 2 and 2-amino-2-methyl-1-propranol. These studies were all based on gas absorption and were analyzed using the methodology of gas absorption with fast pseudo-first order reaction.…”
