Kinetics of CO2 Reaction with Amino-Butanol and Piperazine Using Stopped-Flow Apparatus

Abstract

This research project focuses on the kinetics of CO2 reaction with Amino-butanol (AB) and Piperazine (PZ) for carbon capture. The study examines the CO2 reaction rate of different concentrations of the AB-PZ solution (0.2, 0.4, and 0.6 mol/L) at different temperatures. The results reveal that increasing the concentration of the AB-PZ solution enhances the CO2 reaction rate at higher temperatures, and the 0.6 mol/L solution showed the highest efficiency compared to the lower concentration solutions. At 323 K, the CO2 reaction rate of the 0.6 mol/L solution was significantly higher than the efficiency of the 0.2 and 0.4 mol/L solutions. The temperature also has a significant effect on the CO2 reaction rate, with higher temperatures resulting in higher reaction rates. Moreover, the study suggests that AB-PZ solution could be an effective solution for carbon capture and further optimization of solvent concentration and temperature could lead to even higher reaction rates. The results show that increasing the concentration of Amino Butanol and Piperazine in the CO2 capture solution leads to an increase in the reaction rate constant and CO2 capture capacity. The highest CO2 capture values were observed for the 0.6 mol/L AB-PZ concentration, indicating its potential as a CO2 capture solvent. In conclusion, this study demonstrates the potential of AB-PZ solution as an effective carbon capture solvent. The results provide insights into the factors that affect CO2 reaction rates and CO2 capture capacity, and suggest that optimization of solvent concentration and temperature could lead to even higher efficiency.
