A set of experiments was carried out for the fixed bed catalytic reactor to study the reactor dynamics.
Kinetics is studied with reactor which was diluted with inert material to maintain the isothermal condition.
Based on experimental kinetics data, the steady and transient behavior was investigated.
Dynamics described above was examined by step change and was found to have the very different behaviors for two input variables.
Self-tuning control theory was applied to control the yield as manipulating the contact time.
Simulation results have shown that single-variable self-tuning controller has been found in good control results under simple estimator model having no time delay.
However, the different response of contant time and bath temperature made it impossible to control yield and hot spot temperature simultaneously.
As simulating the modified algorithm for multivariable self-tuning controller, the improved results and several unresolved problems were presented.
