REACTOR AND PROCESS FOR PARAFFIN DEHYDROGENATION TO OLEFINS

Disclosed herein is a method and apparatus for dehydrogenation of a paraffin comprising: providing a dehydrogenation reactor comprising an integrated fluidized bed reactor and a regenerator reactor, wherein the integrated fluidized bed reactor has a first longitudinal axis and comprises an inner surface defining an interior space, wherein the regenerator reactor has a second longitudinal axis and is positioned at least partially within the interior space; activating a deactivated catalyst present in the regenerator reactor by performing a exothermic catalyst regeneration reaction to produce an activated catalyst and heat; transferring the heat to the integrated fluidized bed reactor; and dehydrogenating a paraffm present in the integrated fluidized bed reactor by performing an endothermic reaction with a catalyst, the paraffm, and at least a portion of the transferred heat to forma dehydrogenation product.
