High cost and high energy penalty for CO uptake from flue gases are important obstacles in large-scale industrial applications, and developing efficient technology for CO capture from technical and economic points is crucial. Ionic liquids (ILs) show the potential for CO separation owing to their inherent advantages, and have been proposed as alternatives to overcome the drawbacks of conventional sorbents. Chemical modification of ILs to improve their performance in CO absorption has received more attention. Deep eutectic solvents (DESs) as a new generation of ILs are considered as more economical alternatives to cope with the deficiencies of high cost and high viscosity of conventional ILs. This Review discusses the potential of functionalized ILs and DESs as CO sorbents. Incorporation of CO -philic functional groups, such as amine, in cation and/or anion moiety of ILs can promot their absorption capacity. In general, the functionalization of the anion part of ILs is more effective than the cation part. DESs represent favorable solvent properties and are capable of capturing CO , but the research work is scarce and undeveloped compared to the studies conducted on ILs. It is possible to develop novel DESs with promising absorption capacity. However, more investigation needs to be carried out on the mechanism of CO sorption of DESs to clarify how these novel sorbents can be adjusted and fine-tuned to be best tailored as optimized media for CO capture.

The increasing demand for multi‐task green solvents has spurred the development of next‐generation liquid media such as deep eutectic solvents (DESs), which have recently attracted increased attention. DESs are mixtures of salts and complexing agents, having freezing points lower than those of starting individual components. Similarly to ionic liquids, DESs exhibit distinctive properties such as chemical and thermal stability, biodegradability, non‐flammability, and cost effectiveness. These features account for their wide range of applications, e.g. as extractants, reactants, catalysts, reaction media, additives, and lubricants. This review summarizes the recent research efforts directed at exploring the potential applications of DESs in various chemical processes. With the rapid publication of reports on this new generation of solvents, other roles also are expected to be seen sooner or later. © 2017 Society of Chemical Industry

“…Choline chloride salt may also form DESs with carboxylic acids and polyols [85,91]. Choline chloride may form DESs with levulinic acid/furfuryl alcohol for which detailed CO 2 loading capacity data can be found in [92]. Several potential DESs have been reviewed by [93] including multiple halide slats and hydrogen bond donors but little process level information has been provided.…”

Innovative advanced solvent based capture processes (ASBCPs) employing sophisticated separation mechanisms have emerged as essential solutions that may dramatically reduce high energy requirement of CO 2 separation in capture plants. This study systematically characterises useful mechanisms of several such ASBCPs, being mostly at relatively low technology readiness levels. Based on improved understanding of these emerging ASBCPs it is shown how they can contribute to achieving energy efficiency benefits and thus increase CO 2 capture efficiency. It is followed by an analysis of practical examples of all ASBCPs recently presented in academic and patent literature. Finally, major challenges of discussed emerging ASBCPs are identified showing potential directions for further research and development. Overall, innovative ASBCPs employ very different mechanisms translating to different energy efficiency benefits in various CO 2 capture applications. The provided technological account along with the identified challenges may be useful for capture process developers which will be able to bring the most promising ASBCPs to higher technology readiness levels and finally they can be employed in the practice.
