Abstract:

Many measures have been proposed to reduce the carbon dioxide emission in the atmosphere, of which minerals-sealing is a permanent and safe way with potential. This paper gives an introduction to the axiom, process, raw material selection and reaction system of minerals-sealing carbon dioxide, compares the pros and cons of reaction systems of three carbonate minerals and sealing factors, finds out several minerals of potential, analyzes the sealing factors such as pressure, temperature, PH, mineral grain size and raw material, etc., and presents sealing measures of potential and the following test focuses. 

Key words: carbon dioxide, mineral-sealing, carbonatization, olivine, wollastonite

摘要：

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。
