    摘要
  • 摘要: 黄河流域是我国重要的生态屏障和经济地带，开展固废综合利用对节约资源、减少碳排放等具有显著的协同效应，同时能够保障黄河流域生态环境保护和高质量可持续发展。因此利用固体废物进行矿物封存是一种经济可行的碳捕获和储存技术。以高炉矿渣为原料，选用CaO为碱激发剂，十二烷基硫酸钠（C12H25NaO4S，SDS）为发泡剂，制备了高孔隙的多孔材料，BET结果表明多孔材料比表面积、孔容、孔径均大于不添加发泡剂的矿渣基材料。探讨了水灰比、CaO用量及泡沫掺量3个单因素对多孔材料固化封存CO2的影响，在单因素实验基础上结合响应面分析法，得到多孔材料的最佳制备条件（水灰比为0.65，碱激发剂用量为12%，泡沫掺量为6.10%）。最优工艺条件制备的多孔材料能够达到91.90 kg/m3的CO2封存性能，实际封存量与理论预测值89.39 kg/m3基本一致。该成果能够为碱激发固废基多孔材料在碳封存领域应用的可行性提供借鉴。
    Abstract: The Yellow River Basin is China's important ecological barrier and economic zone. The comprehensive utilization of solid waste has a significant synergy effect on saving resources and reducing carbon emissions, and at the same time can ensure the ecological environment protection and high-quality sustainable development of the Yellow River basin. Therefore, using solid waste for mineral storage is an economical and feasible carbon capture and storage technology. This study used blast furnace slag as the raw material, CaO as an alkali activator, and sodium dodecyl sulfate (C12H25NaO4S, SDS) as a foaming agent to prepare porous materials with high porosity. The optimum preparation conditions of porous materials were obtained as follows:the water-cement ratio was 0.65, alkali activation amount was 12%, and foam content was 6.10%). The porous material prepared under the optimal process conditions can achieve 91.90 kg/m3 CO2 storage performance, and the actual storage capacity is basically consistent with the theoretical prediction value of 89.39 kg/m3. This study can provide a reference for the feasibility of applying alkaline solid waste materials in the carbon storage field.
