| Popis: | Catalytic naphtha reforming is one of the important industrial processes to produce high-octane gasoline and aromatic hydrocarbons. Catalyst is deactivated by coke formation during this process and it should be regenerated. Modeling of the regeneration process is necessary to get better understanding of the coke burning phenomenon and its effective parameters. Regeneration process can be operated in a shorter duration time and more secure way by the optimization of the parameters with an appropriate model. This study presented a mathematical model to evaluate temperature profile and temperature rise during the catalyst regeneration process in a radial flow fixed bed reactor using Comsol Multiphysics software. The operating process parameters of the coke burning are implemented in the model, and its predicted values have been compared with the industrial data. It was found that the model's predictions were in consistent with the industrial data. |
