Abstract: Systems and methods for catalyst activation in ethylene reactions are described. Systems and methods may include pre-mixing at least one ligand and at least one chromium source in at least one solvent to form a pre-mixed composition; activating the pre-mixed composition with an activator to form an activated composition; and supplying the pre-activated composition to a reactor.

Abstract: Methods for generating a purified catalyst are provided. The method includes performing a reaction in a reaction vessel to generate a liquid catalyst and reaction products, purging the reaction products using an inert gas to form a purged catalyst, freezing the purged catalyst in the reaction vessel, and applying a vacuum to the reaction vessel while the purged catalyst thaws, wherein the vacuum removes residual reaction products to form a purified catalyst. Systems for generating a purified catalyst and a purified catalyst are also provided.
