1. A reactor system for catalytic dehydrogenation of saturated Cx hydrocarbons, where the reactor system comprises:
a reactor disengager;
a reactor within the reactor disengager, where the reactor comprises a reactor zone;
a catalyst riser in fluid communication with the reactor at an upper end of the catalyst riser and in fluid communication with a regenerated catalyst stripper and a steam source at a lower end of the catalyst riser; and
an exit riser in fluid communication with an upper end of the reactor, the exit riser in fluid communication with
at least one cyclone adapted to separate catalyst from reactor effluent;
where the reactor comprises a lower portion thereof that is open to the reactor disengager.
