Process for producing pitch for using as raw material for carbon fibers |
摘要 |
A process for producing a pitch which can be utilized as a raw material for producing carbon fibers is disclosed. The process involves distilling a petroleum heavy residual oil under reduced pressure to produce a reduced pressure distillation residual oil or a reduced pressure distillate oil. The distillation residual oil is subjected to a solvent deasphaltening treatment to produce a solvent deasphaltened oil. The solvent deasphaltened oil or the reduced pressure distillate oil is subjected to solvent extraction to obtain a solvent extraction component. The solvent extraction component is thermally modified to produce the pitch. The pitch can be utilized in a melt-spinning process in order to produce carbon fibers having desirable characteristics.
