    • Processes and systems for making cyclopentadiene and/or dicyclopentadiene include converting acyclic C5 hydrocarbon(s) into CPD in a first reactor to obtain a product mixture, separating the product mixture in a separation sub-system such as compression train to obtain a C5-rich fraction comprising CPD and essentially depleted of hydrogen and C1-C4 hydrocarbons, dimerizing the C5-rich fraction in a dimerization reactor to obtain a product effluent comprising DCPD, followed by separating the product effluent to obtain a DCPD- rich fraction. Multiple-stage of dimerization and separation steps can be optionally used to obtain multiple DCPD-rich fractions of various degrees of purity and quantity. C5-rich fractions from various stages of the process may be recycled to the first reactor, or converted into mogas components after selective hydrogenation. C5-rich fractions and mogas components may be optionally separated to produce value-adding chemicals.
    • 用于制备环戊二烯和/或二环戊二烯的方法和系统包括在第一反应器中将无环C5烃转化为CPD以获得产物混合物,将产物混合物在分离子系统例如 压缩机组以获得包含CPD且基本上耗尽的氢和C 1 -C 4烃的富含C5的馏分,在二聚反应器中将富含C5的馏分二聚化以获得包含DCPD的产物流出物,接着分离产物流出物以获得DCPD - 丰富的分数。 可任选地使用多步二聚和分离步骤来获得不同纯度和量的多种富含DCPD的级分。 来自该方法的各个阶段的富含C5的馏分可以被循环到第一反应器中,或者在选择性氢化之后被转化成熟料组分。 富含C5的馏分和原料成分可以任选分离以生产增值化学品。
