Abstract

The rapid industrial waste generation has heightened the environmental strain associated with its disposal. Carbide slag waste, a byproduct of acetylene gas production, is primarily composed of calcium hydroxide and poses significant environmental challenges due to its high volume and alkalinity. This review explores the valorization of carbide slag waste for CO₂ capture and storage, particularly via its applications in cyclic CO₂ capture and mineral carbonation. Scientific advancements in cyclic CO₂ capture capacity and stability with antisintering strategies and pelletization for industrial applications are highlighted. Furthermore, through a detailed analysis of various mineral carbonation studies, new technological and chemical innovations that enhance carbonation efficiency, reduce energy costs, improve reaction kinetics, and enable the production of high-value materials are summarized. Concisely, even though the utilization of carbide slag waste for CO₂ capture and conversion offers a sustainable pathway, it needs to be studied at a larger scale to evaluate its feasibility and associated challenges.

期刊介绍： Current Opinion in Chemical Engineering is devoted to bringing forth short and focused review articles written by experts on current advances in different areas of chemical engineering. Only invited review articles will be published. The goals of each review article in Current Opinion in Chemical Engineering are: 1. To acquaint the reader/researcher with the most important recent papers in the given topic. 2. To provide the reader with the views/opinions of the expert in each topic. The reviews are short (about 2500 words or 5-10 printed pages with figures) and serve as an invaluable source of information for researchers, teachers, professionals and students. The reviews also aim to stimulate exchange of ideas among experts. Themed sections: Each review will focus on particular aspects of one of the following themed sections of chemical engineering: 1. Nanotechnology 2. Energy and environmental engineering 3. Biotechnology and bioprocess engineering 4. Biological engineering (covering tissue engineering, regenerative medicine, drug delivery) 5. Separation engineering (covering membrane technologies, adsorbents, desalination, distillation etc.) 6. Materials engineering (covering biomaterials, inorganic especially ceramic materials, nanostructured materials). 7. Process systems engineering 8. Reaction engineering and catalysis.
