Abstract
A method for preparing a homogenous catalyst for the production of linear alpha olefins includes: preparing a first pre-catalyst solution comprising a modifier and an organoaluminum compound in a first solvent wherein the first pre-catalyst solution is reacted and stored in a first vessel for a period of time of 1 hour to 90 days; preparing a second pre-catalyst solution comprising a second solvent, a ligand, and a chromium containing compound, wherein the second pre-catalyst solution is stored in a second vessel for a period of time of 1 hour to 90 days; and after a period of time, adding the first pre-catalyst solution to a catalyst pre-formation unit; after the same period of time, adding the second pre-catalyst solution to the catalyst pre-formation unit; forming a homogenous catalyst by mixing the first pre-catalyst solution and the second pre-catalyst solution; adding the homogeneous catalyst to a reaction vessel, wherein the reaction vessel comprises an alpha olefin; and forming the linear alpha olefin by mixing the homogeneous catalyst and the homogenous catalyst.
