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.

Method for preparing linear alpha-olefins

Multinuclear catalyst complex comprising two or more active metal centers and at least one phenoxyimine derivative and at least one substituted cyclopentadienyl, indenyl or fluorenyl derivative, each phenoxyimine derivative being bonded to a cyclopentadienyl, indenyl or fluorenyl derivative forming a ligand framework, the cyclopentadienyl, indenyl or fluorenyl derivative being coordinated with one of the metal centers and the phenoxyimine derivative being coordinated with an active metal center other than the metal center the cyclopentadienyl, indenyl or fluorenyl derivative is coordinated with, and wherein the phenoxyimine derivative is derived from a phenoxyimine compound of the formula wherein Ris hydrogen, alkyl, cycloalkyl, aryl or aralkyl;

Catalyst complex and process for producing multimodal molecular weight polyolefins

The present invention relates to a catalyst precursor for the production of odd olefins having the formula: wherein X and Y are halogen and n is 2 or 3; and to a process for its preparation and a method for oligomerization of ethylene.
