25 Αυγ 2019 · Abstract. The formation of MgCO 3 ·3H 2 O in the CO 2 mineralization system was investigated using Mg (OH) 2 as an intermediate at 20 °C. Liquid and solid analyses were done for qualitative and quantitative composition characterizations of the reacted samples.
1 Δεκ 2011 · Using in situ high-pressure X-ray diffraction, the carbonation of brucite [Mg(OH)2] in wet scCO2 was examined at pressure (82 bar) as a function of water concentration and temperature (50...
30 Αυγ 2013 · The resultant 2D Mg(OH)2 bears a weaker thermal stability and a larger band gap compared with the reference nanoparticles synthesized without ethanol addition.
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. For a given reaction temperature, carbonation conversion showed dramatic increase with increasing H 2 O loading.
