Beschreibung
Zusammenfassung:	A method for removing contaminants from a waste plastics pyrolysis stream containing the contaminants by introducing an effective amount of an additive thereto and separating the contaminants from the stream by a physical process, where suitable additives include, but are not necessarily limited to, crude oil demulsifiers, crude oil wax control additives, crude oil pour point reducers, dispersants/antifoulants, nanoscale metallic oxides, overbased metal oxide carbonates, and combinations thereof.
