DEHYDROGENATION PROCESS

A method of improving the operation a dehydrogenation reactor system having a dehydrogenation reactor defining a dehydrogenation reaction zone and containing a first volume of a dehydrogenation catalyst. The method comprises removing from the dehydrogenation reactor at least a portion of the first volume of the dehydrogenation catalyst; placing in the dehydrogenation reactor having removed therefrom the at least a portion of the first volume a second volume of a high stability dehydrogenation catalyst to thereby provide a second dehydrogenation reactor system; operating the second dehydrogenation reactor system under a dehydrogenation reaction condition; and controlling the dehydrogenation reaction condition so as to provide a desired deactivation rate of the high stability dehydrogenation catalyst.
