【摘要】 CO2的温室气体效应已为全世界环保工作者所重视。CO2的矿物固定即碳酸化是减少其温室气体效应的有效方法之一。从矿物碳酸化的热力学、动力学方面分析了这种方法的可行性以及反应机制、速率影响因素等;总结了其工艺路线、生产成本以及产品的性能、用途等。指出用钢铁工业的废弃物——钢渣固定CO2具有很大的应用前景。更多还原

【Abstract】 The greenhouse effect of CO2 has been paid more attention by the environmental workers all over the world.CO2 sequestrated by mineral to form carbonate is an effective way to reduce the harm.The feasibility of this approach,reaction mechanism and affecting factors of carbonation rate are analyzed in terms of thermodynamics and kinetics.Moreover,the process routes,costs and the performance and use of products are summarized.Finally,it is suggested that iron and steel industrial waste,slag,should be a promising option for developing mineral sequestration.更多还原
