A dynamic model was developed by ECUST for the dehydrogenation of propane and the regeneration of the catalyst Pt-Sn/Al2O3. It is a dynamic process considering the internal and external mass transfer and the heat transfer during the process. An ECUST simulator (open loop) exists in Matlab, which can simulate the 2 phases of operation (dehydrogenation and regeneration). We are interested in the synthesis of the model and using the optimal control (which does not seem to have been studied so far) possibly predictive control, to control the reactor during the two phases operations to maximize overall performance.
