摘　　要：基于分形几何理论，采用静态重量吸附法，研究了催化剂在再生过程中表面形貌的变化规律，籍此建立了变维分形体与流体反应宏观动力学模型，给出了模型的求解方法和分形体形状系数的计算公式。研究结果表明。Based on the fractal geometric theory, the surface appearance of the catalyst during regeneration was studied by adsorption method, and an apparent kinetics model for reactions of changeable dimension fractal particle with fluid was established. The method for solving the kinetics model and the equation for calculating the shape coefficient of fractal particle was presented. The research results showed that the model could predict the reaction course.
