We aim to recycle waste plastics to into naphtha feedstocks through chemical recycling, one of the recycling methods for plastics. Waste plastics was melted and dissolved in hydrocarbon solvent to improve fluidity, and catalytically decomposed with zeolites to selectively obtain naphtha components. Light Gas Oil (LGO) obtained in the petroleum refining process was used as solvent, and polypropylene (PP) was used as a representative of polyolefin. Various Beta zeolites synthesized by different methods were used as catalysts, and we found that the alkali-treated catalyst increased the PP conversion and the naphtha yield.
