摘　　要：介绍了矿石直接碳酸化、矿石间接碳酸化、天然咸水层和改性的咸水溶液等存储二氧化碳的方法,并从操作的复杂程度、工艺要求、运行成本等方面进行了简单评价,得出发展以碳酸盐为碳的最终存在物不仅可以永久储存二氧化碳,而且实现工业化的前景广阔.A significant change in atmospheric CO2 concentration has a variety of serious environmental effects. It is crucial to reduce CO2 emissions . One of CO2 sequestration technologies is mineral sequestration, a way to dispose CO2 in carbonate mineral permanently. The mineral sequestration approaches include direct or indirect carbonation based silicates, captured CO2 in raw or improvement brine. In this article, we discuss these approaches in detail and make a comparison among them on operational complexity, technologic requests, cost and so on. It suggests that the mineral sequestration have a potential perspective.
