Abstract

Using low-cost FCC oil slurry as the raw material, coal tar (CT) and coal tar pitch (CTP) as cocarbonization agents, mesophase pitch was prepared through a co carbonization method. The products and formation mechanisms of the mesophase pitch were analyzed. The properties and structure of the meso-phase pitch were characterized and analyzed using polarizing microscope, softening point, Fourier infrared spectroscopy, thermogravimetric analysis, X-ray diffraction (XRD), and Raman spectroscopy. The results indicated that when the reaction conditions were set at a temperature of 410°C, a pressure of 1 MPa, a reaction time of 6 h, with CT at a ratio of 15% or CTP at a ratio of 10%, the comprehensive performance of the resulting mesophase pitch was optimal. By comparing the performance parameters and images of the products from the FCC-CT-MMP and FCC-CTP-MMP systems, the research team found that an appropriate amount of CTP was more effective than CT in improving product performance. However, once the critical value was exceeded, the negative impact of CTP on the product was more pronounced than that of CT.
