    • 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。
