The disclosure provides processes and systems for fluid catalytic cracking of feed streams including hydrocarbons and varying amounts of mixed waste plastic oil to produce valuable petroleum products, such as light olefins and aromatics. The processes generally include providing a waste plastic pyrolysis oil, treating the waste pyrolysis oil reduce a content of one or more of silicon, chlorine, nitrogen, sulfur, and higher olefin components, providing a hydrocarbon stream, combining the hydrocarbon stream with the waste plastic pyrolysis oil to provide a combined feed stream, and feeding the combined feed stream to a fluid catalytic cracking unit having a catalytic cracking catalyst containing a mixture of HZSM-5 and USY.
