unreacted core model

The random pore model, the unreacted shrinking core modelmodel were tested by the experimental data respectively.

在化学控制区内,实验数据用随机孔模型拟合最佳.

The change of SO2 partial pressure, O2 partial pressure, average porosity and average pore radius of product layer on unreacted core were discussed based on the model. The features of calcination in constant temperature were also discussed.

在本文所建立模型的基础上讨论了未反应核表面SO2、O2分压的变化，产物层平均孔径和平均孔隙率的变化，并且讨论了实验工况难以实现的恒温煅烧特性。

In addition, unreacted core model was applied in studying the chemical reaction rate constant and solid state diffusivity.

另外利用未反应收缩核模型研究了700℃&900℃温度区间CaS氧化反应的化学反应速率常数和扩散系数。

Soda leaching process of roasted samples can be described by the unreacted shrinking core model and is controlled by internal diffusion; the apparent activation energy is 51.75kJ/mol.

钙化焙烧渣碳酸钠浸出过程可用未反应收缩核模型来描述，在浸出过程中受扩散控制，反应的表观活化能为51.75kJ/mol。
