Method for preparation of homogenous catalyst for selective 1-hexene production

A method for preparing a homogenous catalyst for the production of linear alpha olefins, comprising:

• 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 the period of time of 1 hour to 90 days, adding the first pre-catalyst solution to a catalyst pre-formation unit;
• after the same period of time of 1 hour to 90 days, 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 alpha olefin,
• wherein the first pre-catalyst solution in the first vessel is circulated through a first pump and a first cooler, and returned to the first vessel, wherein the first pre-catalyst solution is maintained at a temperature of 0-50° C.
