摘要:

温室气体二氧化碳大量排放导致全球气候变暖,碳捕集成为当前重要的任务。利用大宗工业固体废弃物作为生产二氧化碳吸附剂的原料,不仅能有效缓解温室效应,而且原料价格低廉,又多位于二氧化碳排放源,可实现大宗固体废弃物的减量化、资源化。综述了钙基二氧化碳吸附材料的吸附机理及应用工艺流程。总结和比较了具有代表性和可用的工业固体废弃物(电石渣、钢渣、粉煤灰)的直接碳化潜力。介绍了几种提高吸附剂吸附性能的改性方法,包括水合改性、酸改性、掺杂改性等,并且对更适合工业应用的造粒工艺进行了简述,以期为高性能工业固体废弃物二氧化碳捕集材料的开发与应用提供重要的理论和技术支持,为研究人员进一步了解其技术进步和发展趋势提供参考。

Abstract:

The massive emission of greenhouse gas CO2 leads to global warming,and carbon capture has become an important task at present.The use of bulk industrial solid wastes as the raw materials for the production of CO2 adsorbents can not only effectively alleviate the greenhouse effect,but also is cheap and mostly located in the source of CO2 emissions,realizing the reduction and recycling of bulk solid waste.The adsorption mechanism and application process of calcium-based CO2 adsorption materials were reviewed,the direct carbonization potential of the most representative and available industrial solid wastes(carbide slag,steel slag,fly ash) were summarized and compared,and several modification methods to improve the adsorption performance of adsorbents were introduced,including hydration modification,acid modification,doping modification,etc.,and the granulation process more suitable for industrial application was briefly described.It was expected to provide important theoretical and technical support for the development and application of high-performance industrial solid waste CO2 capture materials,and provide reference for researchers to further understand its technical progress and development trends.

Key words: industrial solid waste, calcium-based, carbon dioxide capture, sintering resistance
