Dissolution of activated serpentine for direct flue-gas mineralization
(2013)Energy Procedia ~ GHGT-11 Proceedings of the 11th International Conference on Greenhouse Gas Control TechnologiesThe dissolution of thermally activated serpentine (75% dehydroxylated) by direct flue-gas mineralization was investigated at far-from-equilibrium (w.r.t mineral dissolution) flow-through operating conditions. Experiments were performed at moderate partial pressures of CO2 (0.1 bar 2 bar CO2) and temperatures (30 °C 90 °C). Thermal activation enabled the dissolution of serpentine at mildly acidic conditions. Both magnesium and silica were ...Conference Paper -
Carbonation of activated serpentine for direct flue gas mineralization
(2013)Energy Procedia ~ GHGT-11 Proceedings of the 11th International Conference on Greenhouse Gas Control TechnologiesResearch in mineral carbonation has moved towards process concepts that combine the capture of CO2 from flue gas with its conversion into stable carbonates. This requires highly reactive source materials that dissolve under lean CO2 pressures and temperatures. Activated serpentine has been used in this study, and its carbonation potential under flue gas conditions has been investigated. Single-step carbonation experiments were performed ...Conference Paper
