“…Furthermore, the known chemically based reaction between proteins and free amino groups has very limited reversibility by changing the CO 2 pressure [40]. If the CO 2 gas is adsorbed onto protein chemically, desorption by lowering the pressure of CO 2 is difficult without increasing the temperature [41]. Secondly, the amount of CO 2 adsorbed by casein and gelatine decreases when the temperature increases [18].…”

“…Although impregnated polyethylenimine (PEI) CO 2 adsorbents were reported in the 1980s, 454 they gained prominence only since 2002, when Song's group 455 reported on CO 2 adsorption over PEI-impregnated MCM-41 adsorbent, referred to as "molecular basket". As for the effect of water, they found that in the presence of 7.5% CO 2 /N 2 with ca.…”

Carbon capture from large sources and ambient air is one of the most promising strategies to curb the deleterious effect of greenhouse gases. Among different technologies, CO2 adsorption has drawn widespread attention mostly because of its low energy requirements. Considering that water vapor is a ubiquitous component in air and almost all CO2-rich industrial gas streams, understanding its impact on CO2 adsorption is of critical importance. Owing to the large diversity of adsorbents, water plays many different roles from a severe inhibitor of CO2 adsorption to an excellent promoter. Water may also increase the rate of CO2 capture or have the opposite effect. In the presence of amine-containing adsorbents, water is even necessary for their long-term stability. The current contribution is a comprehensive review of the effects of water whether in the gas feed or as adsorbent moisture on CO2 adsorption. For convenience, we discuss the effect of water vapor on CO2 adsorption over four broadly defined groups of materials separately, namely (i) physical adsorbents, including carbons, zeolites and MOFs, (ii) amine-functionalized adsorbents, and (iii) reactive adsorbents, including metal carbonates and oxides. For each category, the effects of humidity level on CO2 uptake, selectivity, and adsorption kinetics under different operational conditions are discussed. Whenever possible, findings from different sources are compared, paying particular attention to both similarities and inconsistencies. For completeness, the effect of water on membrane CO2 separation is also discussed, albeit briefly.
