摘要

工业废物的迅速产生加剧了与其处置有关的环境压力。电石渣废物是乙炔气生产的副产品，主要由氢氧化钙组成，由于其体积大和碱度，对环境构成了重大挑战。本文综述了电石渣在CO2捕集与封存中的应用，重点介绍了电石渣在循环CO2捕集和矿物碳化中的应用。在循环二氧化碳捕获能力和稳定性与反烧结策略和球团工业应用的科学进展突出。此外，通过对各种矿物碳酸化研究的详细分析，总结了提高碳酸化效率、降低能源成本、改善反应动力学和生产高价值材料的新技术和化学创新。简而言之，尽管利用电石渣废物进行二氧化碳捕获和转化提供了一个可持续的途径，但需要在更大的范围内进行研究，以评估其可行性和相关挑战。

Recent advancements in CO2 capture and storage using carbide slag waste: a review of technological and chemical innovations

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.
