摘要： A spinnable precursor from petroleum pitch is obtained by isolating a particular fraction of a molten carbonaceous pitch, which has had at least a portion of the polycondensed aromatic oils normally present in the pitch removed. The deoiled pitch is then subjected to a two-stage extraction in an organic solvent in which it has a reversed solubility curve, followed by thermal treatment. The thus obtained precursor can be directly spun into fiber.

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.

摘要： A low molecular weight, anisotropic pitch consisting of essentially 100 percent mesophase and suitable for spinning into continuous filaments can be prepared by passing an inert gas through an isotropic carbonaceous pitch at a rate of at least 4.0 scfh. per pound of pitch while heating the pitch at a temperature of from about 380.degree. C. to about 430.degree. C. to produce mesophase and simultaneously agitating the pitch so as to produce a homogeneous emulsion of the mesophase produced and the remaining non-mesophase portion of the pitch, said heating and agitation being continued until the pitch has been essentially completely converted to mesophase and the emulsion has been transformed into an essentially single phase system. When examined under polarized light, the pitches of the present invention are seen to consist of a single phase which is essentially completely anisotropic. The fibers spun from such pitch are also essentially completely anisotropic and can be further processed to produce carbon and graphite fibers having a high Young's modulus of elasticity and high tensile strength.
