The study investigates catalytic conversion of polyethylene and polypropylene—in the form of 1–5 wt % solutions in vacuum distillate—to light olefins in the presence of a catalyst based on a mixture of zeolites Y and ZSM-5. The effects of reaction conditions and polymer pretreatment methods on the conversion degree and product selectivity are discussed. At 675°C quantitative conversion of the polyolefins was achieved, and the products mainly consisted of C2–C4 light olefins. The cracking of the polymer solutions enhanced the yield of light olefins compared to the pure vacuum distillate case, the enhancement reaching up to 9.9 wt %, including 5.2 wt % for propylene.
