    • A process for the oxidative dehydrogenation of ethane is disclosed. The process may include: contacting an ethane feed and an oxygen-containing gas in the presence of an oxidative dehydrogenation catalyst in an oxidative dehydrogenation reaction zone under conditions to oxidatively dehydrogenate at least a portion of the ethane to produce a product stream comprising ethylene, carbon oxides, water, and unreacted oxygen and ethane, wherein an oxygen concentration in the product stream is at least 0.1 mol %; contacting the product stream with an oxygen elimination catalyst in an oxygen elimination reaction zone to combust at least a portion of the oxygen; recovering from the oxygen elimination reaction zone an effluent having a reduced oxygen content; separating water from the effluent; separating carbon oxides and any non-condensable gas(es) from the ethylene and the unreacted ethane; and separating the ethylene from the unreacted ethane.
    • 公开了一种乙烷氧化脱氢方法。 该方法可以包括:在氧化脱氢反应区中在氧化脱氢反应区存在下使乙烷进料和含氧气体接触,以使至少部分乙烷氧化脱氢以产生包含乙烯,碳 氧化物,水和未反应的氧和乙烷,其中产物流中的氧浓度为至少0.1mol%; 使产物流与消氧反应区中的消除氧化催化剂接触以燃烧至少一部分氧; 从氧消除反应区回收具有降低的氧含量的流出物; 从流出物中分离水; 从乙烯和未反应的乙烷中分离碳氧化物和任何不可冷凝气体; 并将乙烯与未反应的乙烷分离。
