摘要： 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.

摘要： An improved process is disclosed for producing a unique metals-containing anisotropic pitch suitable for carbon fiber manufacture. Soluble, aromatic-organometallic compounds are added 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. Next, the pitch product is solvent fractionated to separate mesogens which contain metals from the organometallic compounds. The metals-containing mesogens are heated to a temperature sufficient to cause fusion to produce a metals-containing mesophase pitch. In another method, the carbonaceous feedstock is heat soaked to produce an isotropic pitch product containing mesogens and high molecular weight, soluble, aromatic-organometallic compounds are added to the mesogen containing isotropic pitch product prior to solvent fractionation. Metals-containing carbon fibers produced from the mesophase pitch exhibit enhanced stabilization, tensile strength and modulus properties. 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.

摘要： A solvating component for a solvated mesophase pitch. The solvated component includes a mixture of aromatic hydrocarbons having boiling points in the atmospheric equivalent boiling point range of about 285° to about 500° C. (about 550° F.-932° F.). At least 80% of the carbon atoms of the hydrocarbons are aromatic as characterized by carbon 13 NMR. The aromatic hydrocarbons are selected from a group consisting of aromatic compounds having 2 to 5 aromatic rings, substituted aromatic compounds having 2 to 5 aromatic rings wherein said substituents are alkyl groups having 1 to 3 carbons, hydroaromatic compounds having 2 to 5 rings, substituted aromatic compounds having 2 to 5 rings wherein said substituents are alkyl groups having 1 to 3 carbons, and mixtures thereof.

摘要： This invention relates to low melting solvated mesophase pitches which are suitable for spinning into carbon fibers. The solvated mesophase pitches have a lower melting point than conventional mesophase pitch but remain substantially anisotropic. The solvated mesophase can be produced as an intermediate during solvent fractionation or supercritical solvent fractionation of mesogen-containing isotropic pitches. The process is enhanced through the ability to recover pseudomesogens with an increased average molecular weight which, in combination with the solvent content, provides a fusible mesophase capable of being spun directly into infusible oriented anisotropic carbon fibers.
