1 Αυγ 2022 · MgO-based sorbents have seen a boost in activity since the discovery of molten alkali metal salt promoters, and yet, they practically remove CO 2 from a gas stream efficiently only at very high pressures (p > 10 bar), rendering them suitable for precombustion, but not for postcombustion CO 2 capture schemes.
3 Ιουλ 2020 · Here the authors proposed the use of magnesia (MgO) in ambient looping processes to remove CO2 from the air and they found that the proposed approach will cost $46–195 tCO2−1 net removed from ...
A novel sorbent consisting of Mg (OH)2 was developed for carbon dioxide (CO2) capture at 200−315 °C suitable for CO2 capture applications such as coal gasification systems.
12 Ιαν 2021 · The rationale for removing CO 2 from the atmosphere (“air”) via water is straightforward: water contains nearly 150 times more CO 2 than air per unit volume (Figure 1). Thus, the approach exploits mineralization reactions to achieve carbon sequestration and storage, while bypassing the capture (“CO 2 concentration”) step.
28 Ιουν 2024 · Ocean alkalinity enhancement (OAE) reduces the concentration of dissolved carbon dioxide (CO 2) in seawater, leading to atmospheric carbon dioxide removal (CDR). Here we report laboratory ...
