A PROCESS FOR CATALYTIC DEHYDROGENATION

The invention relates to a process for catalytic dehydrogenation comprising:catalytically dehydrogenating a hydrocarbon feed in the presence of a dehydrogenation catalyst in a fluidized bed catalytic dehydrogenation reactor to produce a product stream comprising used catalyst and at least one dehydrogenated hydrocarbon;separating the used catalyst from gaseous components of the product stream;passing used catalyst to a reactor recycle catalyst fluidization section and to a stripping section separate from the catalyst fluidization section;in the catalyst fluidization section, mixing a fluidization gas comprising methane, natural gas, ethane, hydrogen, nitrogen, or any combination thereof with the used catalyst stream passed to the catalyst fluidization section to form a catalyst recycle stream;in the stripping section, contacting a stripping gas with the used catalyst passed to the stripping section to produce a stripped used catalyst;recycling the catalyst recycle stream either directly or indirectly into the fluidized bed catalytic dehydrogenation reactor; andpassing at least a portion of the stripped used catalyst to a catalyst regeneration process.
