Numerical Simulation of Heat Transfer for the Ethyl Benzene Dehydrogenation Catalyst in the Kiln

In industrial reactors, the chemical or physical transformations are always expected to occur in the best way, so the performance controlling processes associated with mixing of reactants, heat transfer, contacting of multiple phases, mass transfer, chemical reactions, and phase changes are important. In this paper the heat transfer simulation of the gas-solid multiphase flow in ethylbenzene dehydrogenation catalyst kiln, heat conduction, convection and radiation involved, has been expressed by using the computational fluid dynamics (CFD) method. The present study can contribute to our better understanding of the heating process and at the same time, the thermal power distribution and temperature variation of the fluid and catalyst particles can provide guidance for the kiln design.
