Abstract

See full text

Processes for producing ethylene-based polymers and oligomers from ethanol include the steps of contacting the ethanol and a catalyst to produce a reaction mixture containing ethylene, wherein a first portion of the ethanol is derived from a biomass and a second portion of the ethanol is derived from a plastic, a mixed solid waste stream, or a combination thereof, separating at least a portion of the ethylene from the reaction mixture, and contacting ethylene with a suitable polymerization or oligomerization catalyst composition to produce the ethylene polymer or ethylene oligomers. A related process for producing ethylene-based polymers and oligomers uses a first ethylene feed derived from ethanol and a second ethylene feed derived from a plastic, a mixed solid waste stream, or a combination thereof.
