O2／CO2气氛下碳酸钙颗粒分解特性模拟研究

摘要

Combining heat transfer,mass transfer and the principle of chemical kinetics describe the decomposi-tion of limestone in O2/CO2 atmosphere firstly and it fits well with the following experiments. On this basis,the effect of different CO2 concentration on the alteration of the specific area and pore volume were discussed.%结合传质传热和化学动力学原理，首先描述了碳酸钙颗粒在O2/CO2气氛下煅烧情况，模拟结果与实验结果比较吻合，在此基础上模拟分析了碳酸钙颗粒在不同CO2浓度下的转化率和比表面积、孔隙率变化情况。
