Molliwu said that compared with traditional carbon capture methods, the technology of steel slag capturing CO2 from cement kiln flue gas to prepare carbon sequestration auxiliary cementitious materials has many advantages, and it is one of the most economical, safe and efficient carbon sequestration methods.
From the point of view of carbon capture, compared with the adsorption-desorption-storage carbon capture method which has been studied more at present, the biggest advantage of this technology is that it can be used immediately after capture, and there is no need to find another way to use carbon.
From an economic point of view, the product of the reaction between carbon dioxide in the flue gas and steel slag can be directly applied to the production of cement or concrete, which further reduces the cost of carbon capture and creates real benefits for enterprises; at the same time, the steel slag is utilized as a resource, which achieves the goal of "killing two birds with one stone".
"This technology solves the problem of how to apply steel slag safely, efficiently and on a large scale in building materials, and strongly promotes the low-carbon development process of cement concrete materials." Mo Liwu said that in order to achieve the national "3060 double carbon target", the future demand for carbon reduction will be huge, and the low-carbon development of building materials is a clear and inevitable direction. As one of the most economical, safe and efficient carbon sequestration methods, the technology of using steel slag to capture CO2 from cement kiln flue gas to prepare auxiliary cementitious materials for carbon sequestration has a very broad application prospect.
Green development is the solemn mission of the cement industry, and energy saving and carbon reduction is a subject that every cement enterprise can not bypass. On September 12-13, 2023, China Cement Network will hold the "2023 Cement'Double Carbon 'Conference and the 10th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference" in Zhengzhou, Henan Province. At that time, Professor Mo Liwu of Nanjing University of Technology will make a brilliant sharing on the theme of "Key Technologies for Preparing Carbon Sequestration Auxiliary Cementitious Materials and Low Carbon Cement from Steel Slag Capturing Cement Kiln Flue Gas CO2 ".
After the meeting, we will organize a visit to Jiyuan Zhonglian Cement Co., Ltd. "The world's first production line for carbon sequestration auxiliary cementitious materials and low-carbon cement from flue gas CO2 of steel slag capture cement kiln". For more information, please sign up!
