Abstract:

The development of CO2 capture, utilization and storage (CCUS) technology represents a critical step toward mitigating the rising global CO2 concentration. Among various approaches, chemical absorption stands out as a particularly important CO2 capture technique. However, traditional chemical absorption methods are hindered by limitations such as short operational lifespans, high energy consumption and corrosive effects. Deep eutectic solvents (DESs) have emerged as a promising class of novel CO2 chemical absorbents thanks to their exceptional physicochemical properties and environmental friendliness. This paper reviewed the current research progress on DESs in the field of CO2 capture, exploring their definitions, physicochemical properties and application categories. Furthermore, it examined key parameters influencing the CO2 capture performance of DESs including the selection of hydrogen bond acceptors (HBAs) and hydrogen bond donors (HBDs), molar ratios, moisture content, temperature and pressure. Finally, this paper synthesized findings on various types and performances of DESs, proposing a molecular design strategy for developing DESs with enhanced CO2 capture efficiency. The goal was to provide a scientific foundation for advancing the development and optimization of DESs technology, facilitating the application of green solvents in CO2 capture and contributing to sustainable development.

Key words: CO2 capture, deep eutectic solvents, hydrogen bond donors, hydrogen bond acceptors, molecular design

摘要:

CO2捕集、利用和封存(CCUS)技术的开发是遏制全球CO2浓度增高的关键措施。其中以化学吸收为代表的CO2捕集技术尤为关键,然而传统化学吸收方法存在着低寿命、高能耗与腐蚀性等问题。低共熔溶剂(DESs)以其优异的物理化学性质及环境友好性,已成为开发新型CO2化学吸收剂的热点。本文总结了DESs在CO2捕集领域的研究现状,并深入探讨了其定义、物理化学特性及应用分类。随后进一步分析了影响DESs捕集CO2性能的因素,包括氢键受体(HBAs)和氢键供体(HBDs)的选择、摩尔比、水分含量、温度和压力等。最后,综合现有DESs种类及性能,提出了高效捕集CO2的DESs分子设计策略,旨在为未来DESs的开发和技术优化提供科学依据,以推进绿色溶剂在捕集CO2和促进可持续发展中的应用。
