30 Αυγ 2013 · This study investigated the pathways of H 2 O enhanced Mg(OH) 2 carbonation at elevated temperatures and CO 2 pressures (up to 673 K and 1.52 MPa) in the presence of steam and in the slurry phase.
1 Οκτ 2021 · Highlights. •. Weak chemical adsorption of CO 2 molecule on MgO surface is significantly increased by the presence of H 2 O. •. Defects formed by dehydration dramatically improved CO 2 adsorption on Mg (OH) 2 surface with formation of carbonate-like structure. •.
Abstract. The mechanisms involved in the natural formations of dolomite (CaMg (CO 3) 2) and magnesite (MgCO 3) have endured as challenging research questions over centuries, being yet a matter under investigation in multiple fields.
29 Αυγ 2014 · Comparison of hydroxide‐based adsorbents of Mg(OH) 2 and Ca(OH) 2 for CO 2 capture: utilization of response surface methodology, kinetic, and isotherm modeling.
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.
3 Ιουλ 2020 · The KOH sorbent reacts with CO 2 in air to produce aqueous potassium carbonate (K 2 CO 3). K 2 CO 3 then reacts with Ca(OH) 2, produced by calcining solid CaCO 3, to reproduce KOH and...
4 Φεβ 2021 · Here we show a novel low-carbon method of producing Mg(OH)2, from globally abundant olivine-rich silicate rocks.
