    Abstract: Disclosed herein is a process for producing isoprene that includes reacting a mixed C4 metathesis feed stream comprising isobutylene and at least one of 1-butene and 2-pentene in a first metathesis reactor in the presence of a first metathesis catalyst under conditions sufficient to produce an intermediate product stream comprising at least 30 wt. % 2-methyl-2-pentene based upon the olefin content of fresh feed in the mixed C4 feed stream, and at least one of ethylene and propylene, separating the 2-methyl-2-pentene, subjecting the separated 2-methyl-2-pentene to pyrolysis to produce a reaction product stream comprising isoprene, and separating the isoprene into an isoprene product stream using fractionation. A system used in producing isoprene is also disclosed.

    Abstract: Embodiments disclosed herein provide processes for upgrading the hexene stream to valuable end products, including ethers, high purity 1 -hexene, and, alternatively, high purity isohexene. Hexene upgrading may be performed in embodiments disclosed herein by first removing isohexene from the admixture. The isohexene may undergo etherification with one or more alcohols, facilitating the separation of the isohexene (in the form of an ether) from the normal hexenes. Second, the normal hexenes may be isomerized to convert internal hexene olefins (2 -hexenes and 3 -hexenes) to the desired alpha olefin, 1- hexene. The 1 -hexene may then be separated from unreacted components to yield a high purity 1 -hexene product.

    Abstract translation: 本文公开的实施方案提供了将己烯流升级至有价值的最终产物的方法，包括醚，高纯度1-己烯，以及高纯度异己烯。 通过首先从混合物中除去异己烯可以在本文公开的实施方案中进行己烯升级。 异己烯可以与一种或多种醇进行醚化，有利于将异己烯（以醚的形式）从正己烯中分离出来。 其次，正己烯可异构化以将内烯烃（2-己烯和3-己烯）转化为所需的α-烯烃1-己烯。 然后可将1-己烯与未反应的组分分离，得到高纯度1-己烯产物。

    Abstract: Processes and systems for producing linear alpha olefins are described herein. One embodiment is a process comprising: a) separating a mixed butene stream comprising 1 -butene and 2-butene into an overhead 1 -butene stream and a bottoms 2-butene stream in a butene distillation column, a portion of the bottoms 2-butene stream being separated to form a butene reboiler stream that is heated and vaporized in a reboiler and returned to the butene distillation column, (b) subjecting at least a portion of the overhead 1 -butene stream from (a) to catalytic metathesis to produce an effluent including 3-hexene, (c) isomerizing 3-hexene from (b) to produce a mixed hexene stream comprising 1 -hexene, 2-hexene and 3-hexene, (d) separating the mixed hexene stream in a hexene fractionation tower to form a 1 -hexene vapor overhead stream that is condensed in a cooler and a bottoms stream comprising 2-hexene and 3-hexene, and (e) using heat obtained by condensing the 1 -hexene vapor overhead stream of (d) to heat the butene reboiler stream of (a). Another embodiment is a superfractionation process. Corresponding systems are also disclosed.
