Cascade high-value utilization method of waste tire derivative oil

The invention provides a cascade high-value utilization method of waste tire derivative oil. The method comprises the following steps: firstly, filtering the waste tire derivative oil to remove a large amount of cracked carbon black mixed in a cracked oil product due to airflow fluctuation caused by pressure change in a cracking reaction kettle in the cracking process of waste tires; then primarily distilling the filtered derivative oil to obtain a light component (IB-205 DEG C), a medium component (205-365 DEG C) and a heavy component (larger than 356 DEG C). The high-valued application process of the waste tire derivative oilis realized through different technical means by utilizing the component characteristic difference of the three derivative oil components, so that not only can the pollution problem caused by the waste tire derivative oil be solved, but also the profit of a waste tire cracking enterprise can be remarkably improved, and the development of the waste tire cracking industry is greatly promo
