Abstract

Carbon dioxide (CO2) has been widely recognized as one of the greenhouse gases (GHGs) in the atmosphere. GHGs cause global warming, which will bring a lot of problems and irreversible changes. To curb CO2 emissions, much effort has been done. There are many technologies available for CO2 capture, such as amine scrubbing, pressure or temperature swing adsorption, membrane separation, and many solvents and absorbents that have been proposed for CO2 capture (e.g., zeolite, silica materials, graphene, activated carbon, etc.) at every stage (pre-combustion, post-combustion, oxy-combustion). However, these materials have their own drawbacks. Hydrophobic deep eutectic solvents (HDES) is a green alternative that we propose due to its low toxicity, biodegradability, low costs, and availability for large-scale production. This research examines the thermo-physical properties of select HDES and the CO2 capture efficiency and CO2 selectivity from CO2 and N2.
