    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.

    摘要： A high activity and high stability dehydrogenation catalyst, its manufacture and its use. The catalyst comprises an iron ox:de component having a low titanium content, wherein the iron oxide component is made by the heat-treating of a yellow iron oxide precipitate made by precipitating from a solution of an iron salt the yellow iron oxide precipitate and, optionally, an additional dehydrogenation catalytic component, wherein the iron oxide based dehydrogenation catalyst composition has a low concentration of titanium. The low titanium containing iron oxide based dehydrogenation catalyst is used in the dehydrogenation of dehydrogenatable hydrocarbons.
