| Abstract: | 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. |
