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...
cium hydroxide (Ca(OH) 2) to produce solid calcium carbonate (CaCO 3)2. The CaCO 3 is calcined in an oxy-fired calciner to release CO 2. Keith et al.20 propose a continuous looping...
3 Ιουλ 2020 · Here we detail a land-based enhanced weathering cycle utilizing magnesite (MgCO 3) feedstock to repeatedly capture CO 2 from the atmosphere. In this process, MgCO 3 is calcined, producing...
1 Δεκ 2014 · CO 2 removal efficiency and absorption capacity (C:Mg ratio) were used to evaluate the absorption performance. Carbon dioxide removal efficiency increases with the increase of liquid height in the column, while the other parameters affect the efficiency in a more complex way.
1 Δεκ 2014 · Abstract. The present work includes the absorption of CO 2 with Mg (OH) 2 slurry in a bubble column reactor under semi-batch mode.
A novel sorbent consisting of Mg(OH) 2 was developed for carbon dioxide (CO 2) capture at 200−315 °C suitable for CO 2 capture applications such as coal gasification systems.
30 Μαρ 2022 · A comparison of the energy barriers and reaction pathways of these mechanisms shows that the carbonation of MgO is hindered by the presence of H 2 O molecules, while the carbonation of Mg (OH) 2 is hindered by the formation of initial carbonate and hydrate layers as well as presence of excessed H 2 O molecules.
