| Abstract Scope |
Mineral carbonation has garnered widespread attention as an effective carbon emission reduction measure in the context of the low-carbon era. This study focuses on typical metallurgical solid wastes such as steel slag, tailings slag, and desulfurization ash as research objects, investigating the synergistic coupling and carbon sequestration of multi-source alkaline solid wastes. The experimental results show that the carbon sequestration rates of steel slag and desulfurization ash are 1.22% and 4.08%, respectively. However, when mixed in a 50% proportion each, the carbon sequestration rate of the mixed solid waste reaches 7.4%. This can be attributed to the alkali activation effect triggered by the synergy of multiple solid wastes and the inhibition of surface passivation. This paper explores the synergistic coupling of solid wastes to enhance carbon sequestration, which holds positive implications for the collaborative mineralization of multiple solid wastes and carbon dioxide emission reduction in the steel industry. |
