A method of operating a dehydrogenation reactor system |
摘要 |
Described is a method for operating and shutting down a dehydrogenation reactor that contains a volume of dehydrogenation catalyst. After termination of the introduction of a dehydrogenation feed into the dehydrogenation reactor that is operated under dehydrogenation reaction conditions, a first cooling fluid comprising steam is introduced into the reactor for a first time period sufficient to cool the dehydrogenation catalyst contained in the dehydrogenation reactor to a second temperature. The introduction of the first cooling fluid is terminated followed by the introduction of a second cooling fluid for a second time period sufficient to cool the dehydrogenation catalyst contained in the dehydrogenation reactor to a third temperature that allows for the handling and removal of the dehydrogenation catalyst from the dehydrogenation reactor. |
