Notes:
An experimental study has been carried out of the in situ thermal degradation of a commercial dehydrogenation catalyst in a fixed-bed reactor. The activity of catalyst particles sampled at different reactor positions after several reaction-regeneration cycles has been related to their time-temperature history, according to the following kinetics: \documentclass{article}\pagestyle{empty}\begin{document}$$ - da_0 /dt = 0.147{\rm exp}(- 73,600/RT)a_0^{2.2} $$\end{document}The above equation represents the loss of activity under coke-free conditions, that is, activity loss due to sintering. The results of the study show that important differences in catalytic activity can be obtained for different positions of a fixed-bed catalytic reactor after several operation-regeneration cycles.
