    • The present invention relates to an in-line method for generating comonomer, such as 1-hexene or 1-octene, from monomer, such as ethylene. The comonomer generated is directly transported, without isolation or storage, to a polyethylene polymerization reactor. The in-line method for generating comonomer includes the steps of providing an in-line comonomer synthesis reactor and a downstream gas/liquid phase separator prior to a polyethylene polymerization reactor; feeding ethylene monomer and a catalyst in a solvent to the comonomer synthesis reactor; reacting the ethylene monomer and the catalyst in solvent under reaction conditions to produce an effluent stream including ethylene monomer and comonomer; passing the effluent stream from the comonomer synthesis reactor to the downstream gas/liquid phase separator to separate a gas stream from a bottom stream, wherein the gas stream is a mixture of ethylene monomer, and comonomer; and passing the gas stream to the polyethylene polymerization reactor to provide the necessary comonomer input. The in-line method is useful in the production of LLDPE, and other branched polyethylene based polymers. Some benefits include process simplification and reduced capital and operating costs.
    • 本发明涉及从单体如乙烯生成共聚单体如1-己烯或1-辛烯的直列方法。 生成的共聚单体直接输送到聚乙烯聚合反应器中,无需隔离或储存。 用于生成共聚单体的在线方法包括在聚乙烯聚合反应器之前提供在线共聚单体合成反应器和下游气/液相分离器的步骤; 将乙烯单体和催化剂在溶剂中加入到共聚单体合成反应器中; 在反应条件下使乙烯单体和催化剂在溶剂中反应,以产生包括乙烯单体和共聚单体的流出物流; 将来自共聚单体合成反应器的流出物流输送到下游气/液相分离器以从底部流分离气流,其中气流是乙烯单体和共聚单体的混合物; 并将气流送入聚乙烯聚合反应器以提供所需的共聚单体输入。 在线方法可用于生产LLDPE和其他支化聚乙烯基聚合物。 一些好处包括流程简化,降低资本和运营成本。

    • A process for oligomerizing at least one heavy olefin having at least 5 carbon atoms per molecule in the presence of at least one co-fed light olefin having less than 5 carbon atoms per molecule is disclosed. The presence of the at least one co-fed light olefin results in increased C6=(C6 olefin) conversion (if present as one of the at least one heavy olefins), increased weight % of C11+ hydrocarbons in the C9+ material of the product and increased cetane of the C9+ material of the product as compared to the oligomerization of the at least one heavy olefin without the co-fed at least one light olefin.
    • 公开了在至少一种每分子具有少于5个碳原子的共同供给的轻质烯烃的存在下,使至少一种每分子具有至少5个碳原子的重质烯烃低聚的方法。 至少一种共同进料的轻质烯烃的存在导致C6 =(C6烯烃)转化率增加(如果作为至少一种重质烯烃之一存在),则C9 +材料中C11 +烃的重量%增加,以及 与没有共同进料的至少一种轻质烯烃的至少一种重质烯烃的低聚相比,产物的C9 +材料的增加的十六烷。
