Beschreibung
Zusammenfassung:	Provided herein are methods and systems for decontaminating and converting a mixed plastic waste feed to a hydrogen-rich stream suitable for hydrocarbon refinery processing. Methods include the depolymerization of mixed plastic waste, removal of inorganic and metal contaminants, and feeding to one cracking unit or several cracking units in series. The products of the hydrocarbon refinery processing are high value chemicals such as C2-C4 olefins and benzene, toluene, xylenes, and ethyl benzene.
