The Carbon Dioxide Capture Potential of Ash and Slag from Waste Incineration Plants

This article explores the potential of using slag from waste incineration plants to capture carbon dioxide (CO2) in gaseous environments. The study investigates the efficacy of slag as an absorbent for CO2 in gas streams. It examines the purification process, CO2 absorption capacity, activation techniques, and CO2 release mechanisms. The findings suggest that slag has significant potential as a CO2 capture material, offering a promising solution for reducing greenhouse gas emissions from waste incineration plants. The research contributes to the development of effective strategies for mitigating climate change by utilizing waste materials for carbon capture and storage. Additionally, the article discusses various methods of enhancing the CO2 capture capability of slag, such as optimizing particle size, modifying the surface properties, and adding activating agents. The authors present experimental results indicating the improved CO2 adsorption capacity of treated slag samples compared to untreated ones. Furthermore, the study investigates the CO2 release mechanisms during the regeneration of the slag material. It examines factors affecting the release efficiency, such as temperature, gas flow rate, and regeneration time. The findings demonstrate the feasibility of using slag as a cyclic sorbent, with the ability to release and capture CO2 repeatedly. This article provides valuable insights into the possibilities of CO2 capture using slag from waste incineration plants in gas environments. The research contributes to the ongoing efforts in developing effective strategies for mitigating climate change and advancing the field of carbon capture and storage.
