Claim 18:
19. A method of performing a fixed bed dehydrogenation process for producing olefins, the method comprising:
controlling a multiple fixed bed adiabatic dehydrogenation based olefin manufacture system that comprises at least three fixed bed dehydrogenation reactors that are configured to share a feed source and configured to dehydrogenate a hydrocarbon to produce an olefin,
wherein each of the at least three fixed bed dehydrogenation reactors comprise a catalyst bed that does not include a heat generating inert material,
wherein the controlling is performed such that a farthest two of the reactors, by distance, from each other are not operated simultaneously in either of dehydrogenation processing and catalyst regeneration processing, and
wherein the size of Houdry lumps formed in the at least three fixed bed dehydrogenation reactors are reduced compared to a method of controlling that is performed such that the farthest two reactors, by distance, from each other are operated simultaneously in either of dehydrogenation processing and catalyst regeneration processing.
