The increasing development of human society, economy and industry has resulted in a growing demand for fossil fuels in various production activities. As a result of burning fossil fuels, a significant amount of greenhouse gases are produced, causing a series of environmental problems, including global warming and extreme weather conditions. According to the sixth assessment report of the Intergovernmental Panel on (DEA) , and methyldiethanolamine (MDEA) . However, these amines still have certain limitations. For example, MEA and DEA are primary and secondary amines with limited CO2 loadings, respectively. In addition, a high level of energy is required for amine regeneration due to the high stability of the carbamate produced by chemical absorptions. Although the tertiary amine MDEA has a large CO2 loading and a low regeneration energy, its chemical absorption rate is slow . In order to address the shortcomings of current organic amines and explore amines with good performance in CO2 loading, regeneration energy, and chemical absorption rate, numerous researchers have studied the influence of organic amine structures on their performances through experiments and modeling methods. For example, Liu et al. investigate the steric hindrance effect on the reaction rate constants of chemical reactions between CO2 and amines that include MEA and its four different substituent products. Singh et al. study the effects of chain length, side chain, number of functional groups (amine groups) and other factors on CO2 absorption rates.
