Fayalite dissolution and siderite formation in water-saturated supercritical CO2
Popis výsledku v původním jazyce
Olivines, significant constituents of basaltic rocks, have the potential to immobilize permanently CO2 after it is injected in the deep subsurface, due to carbonation reactions occurring between CO2 and the host rock. To investigate the reactions of fayalitic olivine with supercritical CO2 (scCO(2)) and formation of mineral carbonates, experiments were conducted at temperatures of 35 degrees C to 80 degrees C, 90 atm pressure and anoxic conditions. For every temperature, the dissolution of fayalite wasexamined both in the presence of liquid water and H2O-saturated scCO(2). The experiments were conducted in a high pressure batch reactor at reaction time extending up to 85 days. The newly formed products were characterized using a comprehensive suite ofbulk and surface characterization techniques: X-ray diffraction, Transmission/Emission MOssbauer Spectroscopy, Scanning Electron Microscopy coupled with Focused Ion Beam, and High Resolution Transmission Electron Microscopy.
