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.
Claims20
A method for improving catalyst performance in an oligomerization of ethylene, the method comprising:
- 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.
A method for improving catalyst performance in an oligomerization of ethylene, the method comprising:
- pre-mixing ((phenyl)2PN(isopropyl)P(phenyl)NH(isopropyl)) and at least one chromium source in toluene 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.
A system for improving catalyst performance in an oligomerization of ethylene, the system comprising:
- a pre-mixing chamber for receiving inputs of one or more ligands, one or more chromium sources, one or more solvents, and one or more activators;
- one or more stirrers;
- and
- a reaction vessel in fluid communication with the pre-mixing chamber for receiving a pre-activated preformation composition.
