为减少大气中二氧化碳的排放量,人们提出了各种各样的处置方式,其中矿物封存是一种永久、安全且潜力巨大的处置方式。介绍了实验研究矿物封存二氧化碳的原理、流程、原料选择以及反应体系,对比分析3种矿物碳酸盐化反应体系的优缺点以及影响矿物封存二氧化碳的因素,总结出几种封存潜力较大的矿物原料,且进一步分析了压力、温度、PH值、矿物颗粒大小和原料等影响矿物封存的主要因素,并提出最具潜力的封存方式和实验下一步研究的方向和重点。
In order to reduce the carbon dioxide emissions in the atmosphere, a variety of disposal methods have been proposed, of which mineral storage is a permanent, safe and potentially viable disposal method. The principle, process, raw material selection and reaction system for the study of sequestration of carbon dioxide by minerals are introduced. The advantages and disadvantages of the three kinds of carbonate carbonate reaction systems and the factors that affect the sequestration of carbon dioxide are compared and analyzed. The main factors influencing the sequestration of minerals were further analyzed, such as pressure, temperature, PH value, the size of the mineral particles and the raw materials. The most potential storage methods and the direction and emphasis of the next research were also proposed.
