摘要
对液、固两相反应中常见的二种反应类型,建立了同时包含有液相反应剂浓度和固相反应物几何面积随反应时间变化的动力学方程。应用此方程处理液、固两相反应比以往文献中不包含反应剂浓度变化的动力学方程准确合理。而且该方程原则上也适用于气、固两相反应。
For two common types of liquid-solid heterogeneous reactions, thekinetic eqtiations have been established which involved both the variation of liquidreactant concentration and the variation of solid reactant geometry with thereaction time. The experimental results show that the kinetic equations are moreaccurate and reasonable than those appeared in previous literatures. Moreover, theyare also suitable for gas-solid heterogeneous reactions in principle.
