Effects of pressure-controlled reaction and blending of PFO and FCC-DO for mesophase pitch
- 8 Downloads
The mesophase pith was synthesized based on effects of a high-pressure thermal condensation and feed (PFO/FCC-DO) blending. The reaction conditions were designed by fluidity and reactivity of each feed during the thermal reaction. The high-pressure thermal condensation process disturbs distillation of the volatile compounds in pyrolysis fuel oil (PFO); the fluidity can be controlled. In the blending process, PFO, which has a high thermal condensation reactivity, and fluid catalytic cracking-decant oil (FCC-DO), which maintains fluidity, interacted with a synergistic effect. Thus, mesophase pitch with a large mesophase content was manufactured by the two above processes.
