Abstract
A system and method for producing 1-butene and ultra-high-molecular-weight polyethylene (UHMWPE), including feeding a catalyst, an antifouling co-catalyst, and ethylene to a reactor, and dimerizing ethylene into 1-butene and polymerizing a relatively small portion of the ethylene into UHMWPE. A product slurry including 1-butene and UHMWPE is discharged from reactor and UHMWPE is removed from the product slurry as a coproduct of the product 1-butene. The coproduct UHMWPE may be a byproduct that is a relatively small amount of the product slurry. The quantity of UHMWPE produced may be small in comparison to the quantity of 1-butene produced.
