| Summary: | An accurate model is required to optimize the
propane dehydrogenation reaction carried out in the
radial moving bed reactors (RMBR). The present study
modeled the RMBR using a plug flow reactor model
incorporated with kinetic models expressed in simple
power-law model. Catalyst activity and coke formation
were also considered. The model was solved numerically
by discretizing the RMBR in axial and radial directions.
The optimized kinetic parameters were then used to predict the trends of propane conversion, temperature, catalyst activity and coke content in the RMBR along axial and radial directions. It was found that the predicted activation energies of the propane dehydrogenation, propane cracking and ethylene hydrogenation were in reasonable agreement with the experimental values reported in the literature. The model developed has accurately predicted the reaction temperature profile, conversion profile and catalyst coke content. The deviations of these simulated results from the plant data were less than 5%. |
