    • A process for producing propylene is disclosed, including: fractionating a mixed C4 hydrocarbon stream to recover a first fraction comprising isobutene and a second fraction comprising 2-butene; contacting the first fraction with a first metathesis catalyst in a first metathesis reaction zone; recovering an effluent from the first metathesis reaction zone comprising at least one of ethylene, propylene, unreacted isobutene, C5 olefins, and C6 olefins; contacting the second fraction and the ethylene in the effluent with a second metathesis catalyst in a second metathesis reaction zone; recovering an effluent from the second reaction zone comprising at least one of unreacted ethylene, propylene, unreacted 2-butene, fractionating the effluent from the first metathesis reaction zone and the effluent from the second metathesis reaction zone to recover an ethylene fraction, a propylene fraction, one or more C4 fractions, and a fraction comprising at least one of C5 and C6 olefins.
    • 公开了一种生产丙烯的方法,包括:将混合的C4烃流分馏以回收包含异丁烯的第一馏分和包含2-丁烯的第二馏分; 在第一复分解反应区中使第一馏分与第一复分解催化剂接触; 回收来自第一复分解反应区的流出物,其包含乙烯,丙烯,未反应的异丁烯,C 5烯烃和C 6烯烃中的至少一种; 在第二复分解反应区中将第二馏分和流出物中的乙烯与第二复分解催化剂接触; 回收来自第二反应区的流出物,其包含未反应的乙烯,丙烯,未反应的2-丁烯中的至少一种,分馏来自第一复分解反应区的流出物和来自第二复分解反应区的流出物,以回收乙烯馏分,丙烯馏分 ,一个或多个C 4馏分和包含C 5和C 6烯烃中的至少一种的馏分。
