Preparation of petroleum based mesophase pitch by precision control of nitrogen flow and reaction temperature |
| 초록 |
We have studied effects of nitrogen flow rate on mesohpase pitch synthesis from a type of petroleum residue, pyrolysis fuel oil (PFO). A distillation method was applied to synthesize petroleum pitch; heat treatments were performed in a 0.5 L autoclave type of reactor under nitrogen gas flow and effects of temperature were studied. To investigate the influence of nitrogen flow rate on growth rate of mesophase sphere, gas flow rate was preciously controlled from 100 to 800 cm3/min. The resultant pitches were characterized by using a polarized light microscopy and a thermogravimetric analysis instrument. Additional pitch characteristics such as softening points and quinoline insoluble contents of the experimental pitches were also examined. |
