From September 23 to 24, the 14th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference and the 6th Intelligent Summit Forum were held in Zibo, Shandong Province.
At the meeting, Lu Shoujiang, deputy general manager of Suzhou Shijing Science and Technology Co., Ltd., brought "Introduction to the Application of Carbon Capture Technology and Sharing of Advantages".
Lu Shoujiang said that the annual emission of steel slag in China exceeds 100 million tons, which occupies arable land and pollutes the environment. The country has accumulated 1 billion tons of steel slag, and the utilization rate is less than 30%. Steel slag and other metallurgical solid wastes can be used to capture CO2 in industrial tail gas (cement kiln, etc.) Through special process and special catalyst. After carbon capture treatment, steel slag can be changed into carbon fixation cementitious materials to be used as admixture to produce low-carbon building materials, which is an important means to realize the resource utilization of steel slag. Carbon capture technology
of Shijing Science and Technology uses steel slag to capture and solidify CO2 in flue gas of steel, cement and power industries. Olves the problem of the stability of the steel slag and realizes the resource utilization of the solid waste. The prepared carbon fixation auxiliary cementing material can be used as a novel carbon fixation high-quality admixture for cement production. Realize the substitution of low-carbon cement production and related products, prepare carbon fixation high-efficiency composite admixture in cooperation with other low-cost industrial solid wastes, replace mineral powder in concrete production, and improve the performance and quality of concrete.
