Review of carbon capture absorbents for CO ₂ utilization

Carbon capture technologies have been recognized as a potential alternative to alleviate global warming. and storage (CCS) is preferred over carbon conversion utilization (CCU) due its lower operating costs higher CO2 reduction capability. Nevertheless, has the be more economical if value-added products are produced. This highlights importance of assessing routes alternatives in management. review paper aims evaluate major CO2-capturing absorbents including amine, hydroxide, ionic liquid, amino acids carbonate absorbents. All show application for except liquids (ILs) their unclear mechanisms. Absorbents that require desorption process include MEA, MDEA, K2CO3 Na2CO3 high absorption capacity. Industries utilized desorbed chemical feedstocks, enhanced oil recovery (EOR) mineral carbonation. For hydroxide CaCO3, unnecessary absorbed can directly produce construction materials. Apart from that, incorporation advanced business models introduced by fourth industrial revolution plausible considerations accelerate development technologies. © 2022 Society Chemical Industry John Wiley & Sons, Ltd.
