Simultaneous olivine alteration and carbonation in CO2-rich geological condition

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

To investigate the mineral change and energy output of the olivine hydration and carbonation processes in carbon rich hydrothermal system, we monitored a reaction between olivine and NaHCO3 fluid at 300oC and 10 MPa. The study showed the addition of NaHCO3 can promote both the olivine alteration and carbonation process. H2 and HCOOH were regarded as the energy output, with the highest yield of 1.13 mmol and 6.45 mmol/L achieved at 1.0 mol/L of NaHCO3 solution in 72 h. Addition of NaOH promotes brucite generation. The whole process was simulated by kinetic pseudo-second-order model.
