Carbon dioxide sequestration using alkaline earth metal-bearing minerals |
摘要 |
A method for mineral sequestration of pollutant gases resulting from the combustion of carbon-based fuels such as carbon and sulfur dioxides is provided and includes, providing a particulate magnesium-containing mineral and exposing the magnesium-containing mineral to a weak acid to dissolve magnesium from the mineral and form a magnesium-containing solution. The surface of the particulate magnesium-containing mineral is physically activated to expose and dissolve additional magnesium into the solution. Pollutant gases such as carbon dioxide are mixed with the magnesium-containing solution. When the pH of the magnesium-containing solution is increased, solid magnesium carbonate is formed.
