    Abstract: The present invention provides a process for thermosetting pitch fibers in reduced times, at low concentrations of oxygen and at higher temperatures than previously possible. Additionally, the present invention provides a pitch fiber which has an oxygen diffusion rate to the center of the fiber which is competitive with the rate of oxidation at the fiber's surface. Further, the present invention provides a high density pitch fiber batt which thermosets without loss of fiber structure.

    Abstract: The present invention provides a blow spinning die particularly suited for spinning solvated pitch into fibers having a random cross-sectional structure. Additionally, the present invention provides a process for blow spinning fibers from solvated pitches. The present invention also provides pitch fibers having a high energy internal molecular structure. Finally, the present invention provides carbon fibers which have a non-radial internal structure.

    Abstract: A metals containing anisotropic pitch suitable for carbon fiber manufacture is produced by adding a soluble aromatic-organometallic compound to a carbonaceous feedstock which is substantially free of mesophase pitch and the resulting composition is heat soaked to produce an isotropic pitch product containing mesogens and soluble, aromatic-organometallic compounds. The pitch product is solvent fractionated to separate mesogens which contain metals from the organometallic compounds and is then heat-treated. In another method, the carbonaceous feedstock is heat soaked to produce an isotropic pitch product containing mesogens and the organometallic compounds are added to the mesogen containing isotropic pitch product prior to solvent fractionation. Alternatively, the solvent fractionation or separation is conducted under supercritical extraction conditions to produce a metals-containing mesophase pitch. Organometallic compounds may be added to the carbonaceous feedstock either prior to or after the heat soak step. The organometallic compound is preferably macrocyclic and most preferably porphyrin derived.
