Abstract

In the face of escalating environmental concerns, particularly related to greenhouse gas emissions, this study delves into the potential of Deep Eutectic Solvents (DESs) as a sustainable alternative in gas separation technologies. Focusing on the significant emissions of CO2, SO2, and H2S from industrial processes, this work reviews the application of DESs for their capture and separation. The investigation on the physical properties of DESs, such as solubility, which is crucial for their efficacy as sorbents. This review includes a comprehensive analysis of various DES formulations, exploring their roles in CO2 absorption, SO2 removal, and the separation of other gases like H2S. Additionally, the study reveals that DESs, characterized by their biodegradability and environmental sustainability, offer promising performance in gas separation, aligning with the principles of green chemistry. This work underscores the importance of DESs as novel sorbents for gas purification and sets a foundation for future research aimed at enhancing their application on a broader industrial scale.

深共晶溶剂作为气体分离的可持续解决方案：小型回顾

面对不断升级的环境问题，尤其是与温室气体排放相关的问题，本研究深入探讨了深共晶溶剂（DES）作为气体分离技术可持续替代品的潜力。针对工业生产过程中大量排放的 CO2、SO2 和 H2S，本研究回顾了 DESs 在捕获和分离这些气体方面的应用。对 DESs 的物理性质（如溶解性）进行了调查，这对其作为吸附剂的功效至关重要。本综述全面分析了各种 DES 配方，探讨了它们在吸收二氧化碳、去除二氧化硫以及分离 H2S 等其他气体方面的作用。此外，研究还揭示了 DES 具有生物降解性和环境可持续性的特点，在气体分离方面具有良好的性能，符合绿色化学的原则。这项工作强调了 DESs 作为新型气体净化吸附剂的重要性，并为今后旨在加强其在更广泛工业规模上应用的研究奠定了基础。
