The present invention relates to a method for oligomerizing olefins including the steps of: carrying out an oligomerization reaction of olefins by injecting an oligomerization transition metal catalyst, a cocatalyst, an olefin monomer and a solvent into a reactor; and injecting, into the reaction product of the oligomerization reaction, a catalyst inactivator including a gaseous inorganic material that contains oxygen.

Method for oligomerizing olefins

Provided is a method for preparing a linear alpha olefin using a chromium-based catalyst, including the steps of: removing oxygen impurities by contacting an olefin with an oxygen adsorbent; injecting the olefin from which the oxygen impurities are removed; a chromium-based catalyst into a reactor; and oligomerizing the olefin in the reactor.

Method for preparing a linear alpha olefin including oxygen removal from the feed

The present invention provides a fouling prevention method and a method for olefin oligomerization, wherein in the method for olefin oligomerization, a predetermined anti-fouling agent is added, thereby minimizing the production of sticking byproducts generated during the reaction and fundamentally preventing the fouling of the byproducts, generated during the reaction, on an inner wall of a reactor.

Fouling prevention method and method for olefin oligomerization

The present invention relates to a method for olefin oligomerization, and can provide a method for olefin oligomerization. The method includes the steps of: introducing an oligomerization transition metal catalyst, olefin monomers, and a solvent into a reactor and performing an olefin oligomerization reaction to produce an oligomer; introducing a catalyst deactivator to a reaction product of the oligomerization reaction to deactivate the catalyst, with the catalyst deactivator including at least one functional group containing at least one selected from the group including oxygen, phosphor, nitrogen, and sulfur and having a number average molecular weight of 400 or more; separating the oligomer through distillation in a distiller; and separating the catalyst deactivator through the bottom end of the distiller.
