Abstract (en)
[origin: WO2008082866A1] An improved process and system for the endothermic dehydrogenation of an alkane stream (1) is described. The process and system of the present invention comprise a back-mixed fluidized bed reactor (4). The alkane stream is dehydrogenated in a single reactor stage by contacting the alkane stream with a back-mixed fluidized bed (44) of catalyst. Deactivated catalyst (38) is withdrawn from the back-mixed fluidized reactor and heated to produce hot regenerated catalyst (36). The hot regenerated catalyst is returned to the back-mixed fluidized bed reactor at a rate sufficient to maintain the back-mixed fluidized bed reactor at substantially isothermal conditions.
