Fluid–Solid Reaction Kinetics for Solids of Non-basic Geometries: Application of the Law of Additive Times in Combination with the Shape-Factor Method

Fluid–solid reactions often occur under the mixed rate control of chemical and mass transfer processes. The results of this work demonstrate that Sohn’s Law of additive reaction times can be used in combination with the non-basic shape-factor method to obtain closed-form conversion–time relationships for initially porous or non-porous solids of any shape under the mixed control of reaction steps. The conversion–time relationships obtained by this method yield close approximations of the exact numerical solutions of the governing equations for all the cases examined.

非基本几何形状固体的流固反应动力学:加法时间定律与形状因子法相结合的应用

流固反应通常发生在化学和传质过程的混合速率控制下。这项工作的结果表明,Sohn 的加成反应时间定律可以与非基本形状因子方法结合使用,以获得混合条件下任何形状的初始多孔或无孔固体的封闭形式转化时间关系。控制反应步骤。通过这种方法获得的转换-时间关系对所有检查的情况产生了控制方程的精确数值解的近似值。
