<p>A method of sequestrating Carbon Dioxide (CO2) comprises reacting a magnesium or calcium silicate-based material with sodium hydroxide or potassium hydroxide to form a mixture comprising a hydroxide of the alkaline earth and a silicate of the alkali metal wherein the reaction is carried out at a pressure of less than 10 Bar, and at a temperature of less than 140-220 °C, the thus produced alkaline earth hydroxide is then reacted with carbon dioxide. The Silicate-based material preferably comprises a naturally occurring Olivine, Serpentine and/or Wollastonite mineral.</p> |
