Abstract

The invention of waste tire-derived pyrolysis oil conversion process (Figure 1) involves a systematic approach, commencing with fractionation in a 1st Separator (Streams: 3, 4, 5) and subsequent treatment. The 250°C+ stream undergoes mild thermal cracking in a Furnace (6), while the 190°C- stream acts as a quench medium. Further separation in a 2nd Separator (13) results in diverse streams (14-18), contributing to process optimization. The 190-300°C stream undergoes mild hydrocracking in a Reactor (22) with specialized catalysts, separating into Hydrogen and Product streams in a 3rd Separator (24). The 4th Separator (27) refines the Product stream, generating valuable fractions (29-31). In a Steam Cracker (32), the Light Naphtha stream (29) undergoes severe thermal cracking, producing C9-chemicals, Pyrolysis Fuel Oil, and C9-200°C stream (33). Further separation in a 5th Separator (34) yields refined fractions (35-37). This process optimizes waste tire oil utilization, providing valuable products and contributing to sustainable waste management.
