Pyrolysis Oils from Used Tires and Plastic Waste: A Comparison of a Co-Processing with Atmospheric Gas Oil

This study aimed to determine the effect of supplied pyrolysis oils (oils obtained from used tyres and depolymerisation plastics) on activity hydrodesulphurisation catalyst. Each oil was added at 20% weight a standard feedstock processed pilot plant reactors under set conditions commercial unit, including an activated Following catalyst stabilisation, material changed mixture with oils. The reaction conditions, particularly temperature, were controlled. results product analyses compared EN 590 for evaluating diesel fuel; hydrogenated mixed fuel meets most requirements. Only density, flash point, distillation curve lubricity have minor deviations, which could be adjusted by treating sample before or after hydrogenation. properties products, in terms low-temperature properties, also investigated. tyre-derived showed improved possibly due higher levels aromatic hydrocarbons. plastics found more suitable use refineries without substantially impacting existing technologies. For oils, temperatures required processing, affect operation.
