摘　　要：建模是以一种简化和理想化的形式来呈现研究对象中的主要特征及本质联系的方法。在氯化法生产钛白工艺中,建模不仅能够直接建立反应设备的模型以分析其结构性能,而且还可以建立工艺过程中的热力学、动力学模型来进行相关理论研究。中国的氯化法生产钛白工艺中,建模主要应用于建立反应设备模型并进行分析预测、对反应区域流场进行数值分析、工艺过程的理论研究以及TiO_2纳米颗粒合成的研究。国际上建模在氯化法生产钛白的应用主要体现在采用第一性原理、密度泛函理论、涡散理论、扩散理论及成核理论等相关模型以加深对氯化法生产钛白中反应机理的认识。Modeling is a kind of method which in the form of simplified and idealized to present the main features and the essential connection of the research object. In the titanium dioxide production by chloride process, not only the modeling can directly build the model of the reactors for analysis of its structural performance, but also the modeling can build the thermodynamics, dynamics model in the process to do the relative theoretical research. In China, in the titanium dioxide production by chloride process, modeling is mainly applied in analytical prediction of reactor model, the numerical analysis of reaction area flow field, the theoretical research of process engineering, and the synthesis research of TiOz nano - particles. Intomationally, in the titanium dioxide production by chloride process, the application of modeling is mainly in deepen the understanding of reaction mechanism in the titanium dioxide production by chloride process by adoption of the first principles, density functional theory, dissipative theory, diffusion theory, the nucleation model and the relative model.
