during the dehydrogenation process and must be regenerated a continuous process includes the ability to continuously regenerate the catalyst in the reactors the process is for the production of propylene and is shown in the fig1 the process includes passing a hydrocarbon gas 10 that is rich in propane through a dryer 20 to create a dry hydrocarbon stream 22 the dried stream 22 is passed to a heat exchanger 30 to cool the reactor products and preheat the feed the preheated feed is passed to a dehydrogenation reactor 40 to generate an intermediate stream rich in propylene 42 the present invention does not need to incorporate a depropanizer as the heavier hydrocarbons can be handled by the reactor design and operating conditions of the present invention however a depropanizer may be included dependent upon the composition of heavier hydrocarbons in the feedstock the intermediate stream 42 is compressed dried and cooled in a treatment section 50 before passing the treated stream 52 to an optional selective hydrogenation reaction zone 60 in one embodiment the treatment section consists of driers for the intermediate stream 42 the selective hydrogenation zone 60 converts dienes and acetylenes to olefins to create a hydrogenated stream 62 the hydrogenated stream 62 is passed to a separation.
