  Disclosed herein are processes, systems, and reaction systems for the oligomerization of ethylene to form an oligomer product in a reaction zone using a catalyst system having i) a chromium component comprising a heteroatomic ligand chromium compound complex of the type disclosed herein, and ii) an aluminoxane. Ethylene can be contacted with an organic reaction medium to form an ethylene feedstock mixture prior to contact with the catalyst system. The ethylene feedstock mixture can be contacted with the catalyst system inside or outside of the reaction zone.

  本文揭示了一种乙烯寡聚反应的过程、系统和反应系统，使用具有i)包括异原子配体铬化合物复合物的铬组分和ii)氧化铝烷的催化剂系统，在反应区域中形成寡聚物产物。在与催化剂系统接触之前，乙烯可以与有机反应介质接触，形成乙烯进料混合物。乙烯进料混合物可以在反应区内或外与催化剂系统接触。

  Disclosed herein are systems and processes which prevent fouling of a reactor inlet of an oligomerization reactor. The systems and processes involve placement of an inlet sleeve around at least a portion of a reactor inlet such that a curtain of inert material flows through an annular space coaxially with respect to an outer surface of the end of the reactor inlet and into the reactor.

  本文公开了防止低聚反应器入口堵塞的系统和工艺。这些系统和工艺包括在反应器入口的至少一部分周围放置一个入口套筒，使惰性材料帘通过与反应器入口端部外表面同轴的环形空间流入反应器。

  Methods for recycling ethylene from a reaction zone effluent stream from an oligomerization reaction zone, in which the reaction zone effluent stream contains an oligomer product effluent having at least 20 mass % octene(s), include a step of separating the reaction zone effluent stream into a first stream containing ethylene and less than 5 mass % C4+ olefins, a second stream containing butene(s) and less than 10 mass % C6+ olefins, a third stream containing at least 96 mass % hexene(s), and a fourth stream containing at least 96 mass % octene(s). The ethylene-rich first stream is recycled into the oligomerization reaction zone, while the recycle of 1-butene and other butenes is reduced significantly.

  从来自低聚反应区的反应区流出物中回收乙烯的方法，其中反应区流出物包含辛烯含量至少为 20 质量％的低聚产物流出物、包括以下步骤：将反应区流出液分离成含有乙烯和小于 5 质量分数的 C4+ 烯烃的第一液流、含有丁烯和小于 10 质量分数的 C6+ 烯烃的第二液流、含有至少 96 质量分数的己烯的第三液流和含有至少 96 质量分数的辛烯的第四液流。富含乙烯的第一股气流被循环到低聚反应区，而 1-丁烯和其他丁烯的循环量则大大减少。
