制备线性α-烯烃的方法
摘要：
本发明涉及一种在溶剂和均相催化剂的存在下通过乙烯低聚来制备线性α-烯烃(LAO)的方法，该方法包括以下步骤：(i)将乙烯、溶剂和催化剂进料到一个低聚反应器中，(ii)使乙烯在该反应器中低聚，(iii)通过一个反应器出口管道系统从反应器中排出含有溶剂、线性α-烯烃、乙烯和催化剂的反应器出口物流，(iv)将反应器出口物流转移到一个催化剂失活和除去步骤中，和(v)使反应器出口物流中的催化剂失活并将其除去，该方法的特征在于，将至少一种有机胺添加到所述低聚反应器和/或所述反应器出口管道系统中。
摘要（英）：

The present invention relates to a method for preparing linear alpha-olefins (LAO) by oligomerization of ethylene in the presence of solvent and homogenous 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, ethylene, and catalyst from the reactor via a reactor outlet piping system, (iv) transferring the reactor outlet stream to a catalyst deactivation and removal step, and (v) deactivating and removing the catalyst from the reactor outlet stream, characterized in that at least one organic amine is added into the oligomerization reactor and/or into the reactor outlet piping system.
