Abstract

A process for producing alpha-olefins in an oligomerization reaction zone comprising: a) feeding a first stream comprising ethylene into the reaction zone; b) feeding a second stream comprising an iron-ligand catalyst and a co-catalyst in a solvent into the reaction zone; c) contacting the ethylene feed with the iron-ligand catalyst and the co-catalyst in the oligomerization reaction zone under oligomerization reaction conditions, including an oligomerization reaction temperature; and d) withdrawing a product stream comprising alpha-olefins and a method for starting up this process.
