Abstract
A method for preparing a homogenous catalyst for use in preparing a linear alpha olefin includes: preparing a first pre-catalyst solution by mixing a chromium source and a ligand in a first solvent, wherein the first pre-catalyst solution is stored in a first vessel; preparing a second pre-catalyst solution by mixing an organoaluminum compound and a modifier in a second solvent, wherein the second pre-catalyst solution is stored in a second vessel; and simultaneously feeding the first pre-catalyst solution and the second pre-catalyst solution directly into a reaction vessel, wherein the reaction vessel includes a third solvent.
