Carbon Dioxide Mineral Carbonation Through pH-swing Process: A Review

Carbon dioxide sequestration in cement kiln dust through mineral carbonation.

Carbon sequestration through the formation of carbonates is a potential means to reduce CO2 emissions. Alkaline industrial solid wastes typically have high mass fractions of reactive oxides that may not require preprocessing, making them an attractive source material for mineral carbonation The degree of mineral carbonation achievable in cement kiln dust (CKD) underambienttemperatures and press...

Carbon Dioxide Sequestration by Direct Mineral Carbonation: Results from Recent Studies and Current Status

Direct mineral carbonation has been investigated as a process to convert gaseous CO2 into a geologically stable, solid final form. The process utilizes a solution of sodium bicarbonate (NaHCO3), sodium chloride (NaCl), and water, mixed with a mineral reactant, such as olivine (Mg2SiO4) or serpentine [Mg3Si2O5(OH)4]. Carbon dioxide is dissolved into this slurry, by diffusion through the surface ...

Permanent storage of carbon dioxide in geological reservoirs by mineral carbonation

Atmospheric CO2 concentration has increased from 280 ppm during pre-industrial times to 380 ppm today as a result of human input, and this is thought to be causing enhanced global warming and ocean acidification1. Between 2000 and 2005, global CO2 emissions from burning fossil fuels averaged 26.4 Gt CO2 yr−1, at or above the highest rates predicted by the Intergovernmental Panel on Climate Chan...
