    • Described herein is a process for producing an alpha olefin by obtaining a feed stream of internal olefins having a first carbon number and alpha olefins having a first carbon number. The olefins are isomerized to increase the quantity of the alpha olefins. The olefins are then fractionated, subjecting the overhead material to catalytic metathesis to produce a mixed olefin effluent of internal olefins having a second carbon number and other hydrocarbons. The first isomerization reactor and fractionator are prepared to receive the olefins having a second carbon number, where the internal olefin intermediate is isomerized in the prepared first isomerization reactor. The second isomerization effluent is fractionated in the prepared first fractionator to separate the alpha olefins having the second carbon number from the internal olefins having the second carbon number. A corresponding system is also described, along with a heat pump that may be incorporated into the process.
    • 本文描述的是通过获得具有第一碳数的内烯烃和具有第一碳数的α-烯烃的进料流来生产α-烯烃的方法。 烯烃被异构化以增加α-烯烃的量。 然后对烯烃进行分馏,对顶置物料进行催化复分解以产生具有第二碳数的其它烃类的内烯烃的混合烯烃流出物。 制备第一异构化反应器和分馏器以接收具有第二碳数的烯烃,其中内部烯烃中间体在制备的第一异构化反应器中异构化。 将第二异构化流出物在制备的第一分馏器中分馏,以将具有第二碳数的α-烯烃与具有第二碳数的内烯烃分离。 还描述了相应的系统,以及可以并入该过程的热泵。
