All the calculated intraparticle concentration gradient, Thiele modulus and the non-isothermal effectiveness factor appeared with good regularities. 由计算所得的粒内浓度梯度,Thiele模数与非等温效率因子呈现出良好的规律性。
The influences of activity distributions on different orders of reaction and effectiveness factors under the ranges of different Thiele modulus were analysed. 分析了不同反应级数的反应受其影响的程度及活性分布在不同西勒模数区域内的影响规律.3种酶活力在人群中均呈正态分布。
Thiele modulus dominating the reaction rate was defined as the function of conversion. 在该模型中,用于决定反应速率控制步骤的Thiele模数定义为转化率的函数。
Using intrinsic and macroscopic ( diffusion-limited) reaction kinetic experimental data and introducing modified Thiele modulus, the paper derived the method of calculating tortuosity factor for irregularly shaped particles. 利用微观、宏观化学反应动力学实验数据,引入修正的THIELE模数,推导出计算非定形颗粒曲折率的方法。
In the high temperature jet flow region and impinging flow region, the Thiele modulus of the char-steam reaction is greater than 6.9, and the pore diffusion has a significant effect. 在高温射流区和撞击区,对于煤焦-水蒸气气化反应,粒径大于200μm时Thiele模数大于6.9,内扩散影响显著。
