摘要
介绍了矿化固碳的方式和发展现状,化学循环矿化的原理和优势,并结合工业应用和实践,从循环助剂、浸出和碳酸化反应工艺优化及碳酸钙产品控制3方面,分析利用固废实现化学循环矿化固碳目前面临的主要技术难度和研究进展。我国已初步形成化学循环矿化的技术体系,但仍需要进一步丰富矿化原料,在关键反应设备开发和放大、能耗和水耗优化、碳酸钙产品质量控制、零废排放以及配套工艺开发等方面继续投入研发,为我国实现碳中和目标提供有力支撑。
The ways and development status of mineralization solid carbonation are introduced,and the principle and advantages of chemical cycle mineralization are described.In combination with application and practice,the main technical difficulties and research progress faced by the utilization of solid waste to achieve chemical cycle mineralization solid carbonation are analyzed from three aspects:additives recycling,leaching and carbonation reaction process optimization and carbonate product control.Generally speaking,China has initially formed a technology system for chemical cycle mineralization,but it is still necessary further enrich the mineralization raw materials,and to continue to invest in R&D in key reaction equipment development and scaling up,energy and water consumption optimization,carbonate product quality,zero waste emission and supporting process development,so as to make a powerful contribution to the realization of China's carbon neutralization goal.
