Summary: The reaction kinetics and molecular mechanisms of CO2 absorption using nonaqueous and aqueous MEA/MDEA/AMP solutions were analyzed. The study found that in nonaqueous solutions, only AMP/MDEA participated in the deprotonation of MEA-zwitterion, while in aqueous solutions, AMP could also react with CO2 through base-catalyzed hydration mechanism in addition to the zwitterion mechanism.

Summary: Polyamines are promising CO2 absorbents due to their sequestration capacity, but their industrial application is hindered by low regeneration efficiency and high energy consumption. This study explores the use of triethylenetetramine and ethylene glycol to develop a nonaqueous absorbent, and the incorporation of ethylene glycol improves absorption performance and reduces regeneration energy. Micron-sized reaction units are developed to enhance CO2 capture and show significant improvement in regeneration efficiency.

Summary: CO2-Binding organic liquids (CO(2)BOLs) are non-aqueous solvents that can reduce the energy consumption of carbon capture processes. These solvents exhibit surprising mass transfer behavior, with the flux of CO2 into CO(2)BOLs decreasing exponentially with increasing temperature. This phenomenon is primarily driven by a shift in reaction equilibrium, reducing the enhancement of CO2 flux by chemical reactions. First-principles surface renewal models accurately replicate the mass transfer data for CO2 absorption into different CO(2)BOLs, and density functional theory calculations identify structural modifications that could improve CO2 flux.

Summary: The study found that the density and viscosity of the novel blended PZ-MPDL solvent increased with higher PZ concentration ratio, and decreased with temperature. On the other hand, the physical diffusivity of CO2 decreased with higher PZ concentration ratio, and increased with temperature. Increasing the PZ concentration ratio was shown to improve the CO2 absorption capacity of PZ-MPDL.

Summary: A poly(tetrafluoroethylene) hollow-fiber membrane contactor was used to absorb CO2 in tertiary amine solutions. The study investigated several influential factors and established a mathematical model to calculate CO2 mass transfer flux and concentration distribution. It was found that partially wetted membrane significantly reduced mass transfer, but the predicted values agreed well with experimental results. In addition, an equation for predicting mass transfer coefficients and flux was developed, showing good agreement with experimental values.
