چکیده

This study explores the application of the point solution concept in analyzing reaction-diffusion processes within porous catalysts, thus offering a novel perspective on this research area. Porous catalysts are of great significance in numerous industrial processes, and understanding the reaction-diffusion mechanisms inside them is crucial for optimizing catalytic performance. Existing methods, such as the homotopy perturbation method, can provide semi-analytical solutions for the entire solution domain; however, they are limited in their ability to accurately capture local behavior at a specific point. The present study proposes an approximate solution that is focused on achieving high accuracy at a specific point. The point solution method is applied to the mathematical equations describing porous catalyst systems and compared with traditional methods. The findings reveal that the point solution concept offers a comprehensive analysis of the impacts of critical parameters (e.g., the Thiele modulus, adsorption parameter, and reaction rate constant) on the reaction-diffusion process at specific points. This analysis unveils local variations and addresses the limitations of traditional methods. However, the application of this concept faces challenges, such as the complexity of porous catalyst systems and difficulties in choosing a good initial solution. Future research directions may include the development of more sophisticated point selection algorithms (AI-powered problem-solving technologies), the improvement of initial guess methods, and the integration with other technologies. This study contributes to a more profound understanding of the intricate systems of porous catalysts and provides a foundation for both theoretical research and practical applications.
