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...

متن کاملMineral sequestration of CO(2) by aqueous carbonation of coal combustion fly-ash.
The increasing CO(2) concentration in the Earth's atmosphere, mainly caused by fossil fuel combustion, has led to concerns about global warming. A technology that could possibly contribute to reducing carbon dioxide emissions is the in-situ mineral sequestration (long term geological storage) or the ex-situ mineral sequestration (controlled industrial reactors) of CO(2). In the present study, w...
متن کاملInvestigations of the Mechanisms that Govern Carbon Dioxide Sequestration via Aqueous Olivine Mineral Carbonation
Coal, in particular, and fossil fuels, in general, are well positioned to supply the world’s energy needs for centuries to come if the environmental challenges associated with anthropogenic carbon dioxide emissions can be overcome. Carbon dioxide sequestration is being actively pursued as an option to reduce CO2 emissions, while still enjoying the advantages of low-cost fossil fuel energy. Mine...
متن کاملField Application of Accelerated Mineral Carbonation
Globally, coal-fired power plants are the largest industrial source of carbon dioxide (CO2). CO2 emissions from flue gas have potential for direct mineralization with electrostatic precipitator fly ash particles in the field. Demonstration scale accelerated mineral carbonation (AMC) studies were conducted at the Jim Bridger Power Plant, a large coal fired power plant located in Wyoming, USA. AM...
