摘要
将温室气体CO2以碳酸盐(如CaCO3、MgCO3)的固体形式永久储存起来,即CO2矿物碳酸化固定,是减少大气中CO2含量,解除温室效应的一种全新方法。从温室气体CO2矿物碳酸化固定所需的原料、化学及热力学、反应动力学机理等方面,分析了此种方法的特点,同时评述了CO2矿物碳酸化固定的6种典型工艺路线,以及国外有关温室气体CO2矿物碳酸化固定的研究热点。最后指出以工业固体废弃物为原料的间接工艺路线是温室气体CO2矿物碳酸化固定的具有较好应用前景的技术途径。
CO2 sequestration by mineral carbonation, namely greenhouse gas CO2 reacting with noncarbonate minerals to form geologically stable mineral carbonates, such as CaCO3, MgCO3, is a new technology for the reduction of carbon dioxide emissions to the atmosphere. In this paper, the optional resources, chemistry, thermodynamics, reaction kinetics as well as mechanisms in the mineral CO2 sequestration were analyzed. Moreover, six representative process routes as well as issues of topical interest regarding the investigation of mineral sequestration were reviewed. Finally, it was suggested that the integrated indirect process route using industrial solid residues should be a promising option for developing mineral sequestration.
