    • The present invention relates to a method for preparing linear alpha olefin comonomers, such as 1-butene, 1-hexene or 1-octene, from ethylene monomer. The comonomer generated is stored on site for use in a subsequent process, such as a polyethylene polymerization reactor. The method includes the steps of feeding an ethylene monomer, and a catalyst in a solvent to one or more comonomer synthesis reactors; reacting the ethylene monomer and the catalyst in solvent under reaction conditions to produce an effluent stream comprising unreacted ethylene monomer, a catalyst in a solvent, and comonomer; passing the effluent stream to one or more downstream gas/liquid phase separators to form a gas stream of unreacted ethylene monomer, and a liquid stream of comonomer, and catalyst in a solvent; recycling to the one or more comonomer synthesis reactors the unreacted ethylene monomer and a portion of the liquid stream; and storing a remaining portion of said liquid stream for subsequent processing of the comonomer. Some of the benefits of the method include process simplification and reduced capital and operating costs from, inter alia,
    • 本发明涉及从乙烯单体制备线型α-烯烃共聚单体如1-丁烯,1-己烯或1-辛烯的方法。 生成的共聚单体存储在现场用于随后的方法,例如聚乙烯聚合反应器。 该方法包括将乙烯单体和溶剂中的催化剂进料到一个或多个共聚单体合成反应器中的步骤; 在反应条件下使乙烯单体和催化剂在溶剂中反应,以产生包含未反应的乙烯单体,在溶剂中的催化剂和共聚单体的流出物流; 将流出物流输送到一个或多个下游气/液相分离器,以形成未反应的乙烯单体的气流,以及溶剂中的催化剂的液体流; 将一个或多个共聚单体合成反应器再循环到未反应的乙烯单体和一部分液体流中; 并存储所述液体流的剩余部分,用于随后处理共聚单体。 该方法的一些好处包括过程简化和减少资本和运营成本,其中除其他外,
