摘要:: 温室气体排放和气候变化问题促使世界各国采取措施降低 CO₂水平，防止其在大气中

上升，从而控制全球变暖。通过碳捕集和储存来有效管理 CO₂，对于安全和永久储存至关重

要，同时也有助于实现碳减排目标。利用碳减排技术降低 CO₂排放，能够为能源安全发展开

辟广泛的新业务领域。其中，CO₂矿化是生产化学稳定的固体钙最有前途的策略之一。文中

系统梳理了CO₂矿化技术的研究进展，重点分析了以工业固体废弃物为原料的矿化路径与反

应机理。当前研究已证实该技术在建筑材料、农业改良及资源回收等领域的应用潜力，多个

中试案例的成功实施为其产业化提供了实践支撑。然而，原料组分复杂性、反应动力学限制

及工艺经济性仍是亟待突破的瓶颈。未来需通过优化反应条件、强化传质过程、开发高附加

值产品等途径提升技术可行性，为推动绿色低碳发展提供关键技术支撑。

The increase in greenhouse gas emissions and the consequent climate change have prompted countries worldwide to

implement measures aimed at reducing CO₂ levels and preventing their accumulation in the atmosphere, thereby mitigating global

warming. Effective management of CO₂ through carbon capture and storage is crucial for its safe and permanent sequestration,

while also contributing to the achievement of carbon emission reduction targets. Employing carbon reduction technologies to lower

CO₂ emissions can open up a wide range of new business areas for the secure development of energy resources. Among these, CO₂

mineralization stands out as one of the most promising strategies for producing chemically stable solid calcium carbonates.

This paper systematically reviews the research progress of carbon dioxide mineralization technology, with a focus on analyzing

mineralization pathways and reaction mechanisms using industrial solid wastes as raw materials. Current research has confirmed

the technology′s application potential in fields such as construction materials, agricultural improvement, and resource recovery. The

successful implementation of several pilot-scale projects provides practical support for its industrialization. However, challenges

such as the complexity of raw material components, reaction kinetic limitations, and process economics remain critical bottlenecks

to be overcome. Future efforts should focus on enhancing technical feasibility by optimizing reaction conditions, intensifying mass

transfer processes, and developing high-value-added products, thereby providing key technological support for promoting green and

low-carbon development.
