Thermal degradation of waste plastics is one method currently being investigated as an alternative to landfill disposal of this increasingly large waste stream. Although the thermal process produces significant quantities of light naphtha range (C6–C14) liquids, there is also a residual fraction that may be considered as a potential feedstock for upgrading. In this study, the fraction of a liquid produced by the thermal degradation process of waste plastics, containing about 29%, +110 °C naphtha chemical, was subjected to thermal reactions. The reactions used a commercial HZSM-5 supported on zeolite catalyst and gave good conversion to naphtha. The process well simulated the experimental data, including experimentally observed trends such as the maximum in naphtha yield.
