Abstract: The present disclosure provides a pyrolysis process for converting an additive-containing plastic comprising a polyolefin polymer to an alkene, an alkane, or a mixture thereof. The process comprises contacting the plastic with a catalyst in a one-pot pyrolysis system at a temperature between about 350° C. and about 500° C.; wherein the catalyst comprises a solid acid selected from the group consisting of HY, HZSM-5, and Al-SBA-15. The present disclosure further provides a one-pot pyrolysis system and uses of a solid acid in the pyrolysis process for converting plastic comprising a polyolefin polymer to an alkene.
