摘要:
The present invention relates to a method for preparing linear alpha-olefins (LAO) by oligomerization of ethylene in the presence of a solvent and homogeneous catalyst, comprising the steps of: (i) feeding ethylene, solvent and catalyst into an oligomerization reactor, (ii) oligomerizing the ethylene in the reactor, (iii) removing a reactor outlet stream comprising solvent, linear alpha-olefins, optionally unreacted ethylene and catalyst from the reactor via a reactor outlet piping system, (iv) dosing at least one additive selected from the group consisting of alcohols, poly-ethylene glycols, polyethylene glycol monoethers, polyethylene glycol diethers, polyamines, amines, amino alcohols and surfactants, (v) transferring the reactor outlet stre con the additive to a catalyst deactivation and removal section, and (vi) deactivating the catalyst with caustic and removing the deactivated catalyst from the reactor outlet stream, wherein the residence time of the additive in the reactor outlet stream prior to mixing with caustic is at least 1 second preferably at least 5 seconds, more preferably at least 10 seconds.
摘要(中):
本发明涉及通过在溶剂和均相催化剂存在下使乙烯低聚制备线性α-烯烃(LAO)的方法,包括以下步骤:(i)将乙烯,溶剂和催化剂进料到低聚反应器中( ii)使反应器中的乙烯低聚,(iii)通过反应器出口管道系统从反应器中除去包含溶剂,线性α-烯烃,任选未反应的乙烯和催化剂的反应器出口流,(iv)给予至少一种选自 由醇,聚乙二醇,聚乙二醇单醚,聚乙二醇二醚,多胺,胺,氨基醇和表面活性剂组成的组,(v)将反应器出口将该添加剂转移到催化剂失活和除去部分,和(vi )用苛性碱使催化剂失活并从反应器出口流中除去失活的催化剂,其中添加剂在反应器外部的停留时间 在与苛性碱混合之前的流量为至少1秒,优选至少5秒,更优选至少10秒。
