메탄, 천연 가스, 에탄, 수소, 질소 또는 이들의 임의의 조합을 포함하는 유동화 가스를, 촉매적 탈수소화 반응기를 통과하고 촉매 리사이클 스트림을 형성하기 위해 촉매 분리 구역을 빠져 나가는 유동화 촉매 스트림과 혼합하는 단계; 및 촉매 리사이클 스트림을 촉매적 탈수소화 반응기로 직접 또는 간접적으로 리사이클링하는 단계를 포함하는, 촉매적 탈수소화 방법이 제공된다. 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.
