Improving the absorption load, high viscosity, and regeneration efficiency of CO2 capture using a novel tri-solvent biphasic solvents of TETA-AMP-1DMA2P

Understanding the Positive Role of Ionic Liquids in CO2 Capture by Poly(ethylenimine)

“…18 The amine absorption method currently stands as the most extensively employed industrial approach for CO 2 capture. 19,20 However, this conventional amine absorption method presents certain inherent issues: (1) the generation of carbamates during the absorption process leads to a significant increase in viscosity; 21 (2) the alkanolamines and physical solvents frequently employed exhibit a high degree of volatility; 22…”

“…Therefore, the capture and storage technology of CO 2 represents a potent means to address the current carbon emissions issue, − bearing significant relevance for CO 2 reduction, carbon peak attainment, and carbon neutrality . The amine absorption method currently stands as the most extensively employed industrial approach for CO 2 capture. , However, this conventional amine absorption method presents certain inherent issues: (1) the generation of carbamates during the absorption process leads to a significant increase in viscosity; (2) the alkanolamines and physical solvents frequently employed exhibit a high degree of volatility; and (3) the reaction rate between alkanolamine solutions and CO 2 is relatively slow, leading to higher energy consumption . Therefore, it is necessary to design a new kind of solvent for the highly efficient absorption of CO 2 .…”
