摘　　要：在改进的热天平上，测定石灰石的热解和固硫反应热重曲线，并经对曲线进行回归处理．给出了石灰石热解的动力学方程；提出石灰石固硫热重曲线的“分段”分析方法。对在不同条件下得到的CaO与SO的反应进行机理分析。The reactions of pyrolysis and desulfurization of limestone were experimented on the improved thermaI balance. on these thermogravity curves, the kinetic equations of pyrolysis of limestone were given .and 'the stage by stage' analysis of desulfurization of limestone was investigated. Mechanism on the reaction of CaO with SO2 obtained under different conditions was analyzed.
