Abstract

The use of fossil fuels is steadily increasing. The thermal power generation industry uses a lot of energy and emits a large amount of greenhouse gases. On the other hand, a desulfurization facility can be installed to remove sulfur content during boiler combustion process of the power plant. Dry desulfurized gypsum generated from dry desulfurization facilities is suitable as a $CO_2$ absorbing material due to the presence of CaO. In this study, the carbonation properties of dry desulfurized gypsum were investigated by carbonizing dry desulfurized gypsum via mixing with water and stirring. As a result of microstructural, XRD and thermal analyses of the carbonized dry desulfurized gypsum, the carbonation age was found to be suitable for 16 h. Dry desulfurized gypsum absorbs about 16% of $CO_2$ per unit weight.
