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
