[0053] According to the present invention, the dehydrogenation reaction of hydrocarbons deactivates the deactivation catalyst during 100 hours of operation before it requires regeneration of the catalyst. Therefore, the activity of the dehydrogenation catalyst is graded by its initial maximum activity and its performance over a period of 5-20 hours on stream.
[0054] In order to demonstrate the advantages obtained with the present invention, a catalyst according to the invention and two prior art catalysts were prepared.
[0055] The first prior art catalyst contained 0.2 wt% tin and 0.7 wt% potassium and the second prior art catalyst contained 0.2 wt% tin and 1 wt% potassium. The catalyst of the invention contains 0.17% by weight tin and 1% by weight potassium. These catalysts are labeled Catalyst A, Catalyst B and Catalyst C, respectively. First, for all three catalysts, spherical alumina supports were prepared using the known oil drop method. The tin component is introd...
