| Abstract: |
| Aromatic-enriched components were obtained from FCC slurry by means of solvent extraction. Both original FCC slurry and aromatic-enriched components were employed to synthesize pitch resin. The properties of raw materials were analyzed using group composition analysis, infrared spectrum and nuclear magnetic resonance spectrum method. The reactivity of FCC slurry to synthesize B-stage pitch resin was investigated through the synthesis of pitch resin. The results show that the concentration of saturates in original FCC slurry is higher than aromatic-enriched components, the homogeneity is bad and the composition of FCC slurry is complex. The reactivity of raw materials was greatly improved after solvent extraction. |
