Patent ID: 8895797

Claim:
A process for dehydrogenation of hydrocarbons comprising: passing a hydrocarbon feedstream comprising paraffins to a plurality of reactor beds, wherein the hydrocarbon feedstream is passed in parallel to the reactor beds, thereby creating a dehydrogenated product stream, and wherein the reactor beds are fluidized reactor beds; passing a regenerated catalyst to the first reactor bed of the plurality of reactor beds; passing catalyst from the first reactor bed to a second reactor bed; passing catalyst from the second reactor bed to a third reactor bed; passing catalyst from the third reactor bed to a regeneration unit, thereby creating regenerated catalyst, wherein the catalyst has been passed through the reactor beds in series, wherein the temperature profile in the reactor beds is such that the temperature of the second bed is greater than the temperature of the first bed, and the temperature of the third bed is greater than the temperature of the second bed; and passing regenerated catalyst to the first reactor bed.
