Transforming Waste Plastic into High-Value Petrochemical and Diesel Fraction Through the Pyrolysis Process
Abstract
Plastics are remarkable materials in the 21st century, owing to their exceptional properties. Waste materials like polypropylene (PP), polystyrene (PS), and polyethylene are precious due to their composition, comprising long chains of hydrocarbon materials. This pyrolysis study explores the promising prospects of converting waste thermoplastics into green liquid petrochemicals, offering a sustainable solution to address both plastic waste and the growing demand for petrochemical feedstocks. Collected green petrochemicals were analyzed by the Fourier transform infrared spectroscopy (FT-IR), GC×GC-MS, and physiochemical properties of diesel, then found diesel fraction with other petrochemicals their carbon ranges spanning C4 to C28. The consisting of LD-PE (25 gm), HD-PE (25 gm), PP (25 gm), and PS (25 gm) plastics, underwent a comprehensive analysis. These materials exhibited a remarkable conversion rate of 91% into liquid petrochemicals and diesel fraction, while light gases constituted 8.80%, with residue accounting for a slightly higher percentage of 0.20%.
