Hybrid solvents based on ionic liquids/deep eutectic solvents for CO2 separation

CO2 separation plays a vital role in reducing emissions to combat climate change, while the available technologies still face challenges, including high costs and intensive energy usage. It is critical develop an energy-efficient cost-effective technology for separation. Ionic liquid/deep eutectic solvent (IL/DES) has drawn significant attention because they are tunable exhibit thermal stability solubility. The based on IL/DES show their potential reduce cost However, viscosity relatively high.In our work, adding cosolvents was used adjust of IL/DES. A universal framework IL/DES-based hybrid solvents separation, from properties determination, thermodynamic modeling, process design evaluation, been built up. Several DESs/ILs interacted with chemically and/or physically were investigated, aiming gas streams different concentrations (biogas, flue gas). detailed comparison performance terms usage respect conventional provided study feasibility. Our research shows that promising reach aim lowing cost, further improvement needed technological breakthrough.
