      Carbon dioxide storage in olivine basalts: Effect of ball milling process 

      Rigopoulos, Ioannis; Petallidou, Klito C.; Vasiliades, Michalis A.; Delimitis, Andréas; Ioannou, Ioannis; Efstathiou, Angelos M.; Kyratsi, Theodora (2015)
      The goal of this study is to propose a cost-effective method for the optimization of the ex situ carbonation of basaltic rocks. The ball milling process was applied to a sample of olivine basalt from the Troodos ophiolite ...

      Carbon sequestration via enhanced weathering of peridotites and basalts in seawater 

      Rigopoulos, I.; Harrison, A. L.; Delimitis, A.; Ioannou, I.; Efstathiou, A. M.; Kyratsi, Theodora; Oelkers, E. H. (2018)
      Enhanced weathering of mafic and ultramafic rocks has been suggested as a carbon sequestration strategy for the mitigation of climate change. This study was designed to assess the potential drawdown of CO2 directly from ...

      A comparative study of the steam reforming of phenol towards H2 production over natural calcite, dolomite and olivine materials 

      Constantinou, D. A.; Fierro, José Luis García; Efstathiou, Angelos M. (2010)
      Pre-calcined (air, 850 °C) naturally occurring calcite, dolomite and olivine materials were studied for phenol steam reforming towards H2 production. The effect of reaction temperature, feed volume flow rate, and hydrogen ...

      Effect of ball milling on the carbon sequestration efficiency of serpentinized peridotites 

      Rigopoulos, I.; Delimitis, A.; Ioannou, I.; Efstathiou, A. M.; Kyratsi, Theodora (2018)
      Mineral carbonation has been suggested as a safe carbon capture and storage (CCS) strategy for the mitigation of climate change. This study investigates the effect of ball milling on the CO2 sequestration capacity of ...

      On the potential use of quarry waste material for CO2 sequestration 

      Rigopoulos, Ioannis; Petallidou, Klito C.; Vasiliades, Michalis A.; Delimitis, Andréas; Ioannou, Ioannis; Efstathiou, Angelos M.; Kyratsi, Theodora (2016)
      The use of solid wastes rich in Ca2+, Mg2+ and Fe2+ for the ex situ sequestration of CO2 could provide an economically and technologically viable option for the reduction of anthropogenic CO2 emissions. Here, we investigate ...
