Abstract:

Sequestration of CO₂ from atmosphere in the form of solid carbonates through mineral carbonation is an option for reduction of CO₂ concentration. In the present study carbon dioxide sequestration has been performed by using sulfatised hydrated mixture of fly ash with calcium bearing material in presence of some chemical activator. Hydrated mixture of both these materials provides a favorable condition for mineral carbonation. TGA study indicates that by suitable conditioning 1ton of carbonated ash absorbs 100kg of CO₂ in atmospheric condition.
 
Keywords –Mineral carbonation, industrial waste, fly ash, hydrated mixture, and CO₂ sequestration.
