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 fibers surface. Further, the present invention provides a high density pitch fiber batt which thermosets without loss of fiber structure.

A system and process for extracting hydrocarbons from a subterranean body of oil shale within an oil shale deposit located beneath an overburden. The system comprises an energy delivery subsystem to heat the body of oil shale and a hydrocarbon gathering subsystem for gathering hydrocarbons retorted from the body of oil shale. The energy delivery subsystem comprises at least one energy delivery well drilled from the surface of the earth through the overburden to a depth proximate a bottom of the body of oil shale, the energy delivery well extending generally downward from a surface location above a proximal end of the body of oil shale to be retorted and continuing proximate the bottom of the body of oil shale. The energy delivery well may extend into the body of oil shale at an angle.

A process for retorting and extracting sub-surface hydrocarbons. The process comprises drilling an energy delivery well extending from the surface to a location proximate a bottom of the hydrocarbons. The hydrocarbons are heated from the bottom to form a retort, the retort extending along a portion of the energy delivery well. A vapor tube is extended to a location proximate the retort, the vapor tube having an entrance corresponding to the region of the retort along the energy delivery well that is nearest the surface exit.

A sub-surface hydrocarbon production system comprising an energy delivery well extending from the surface to a location proximate a bottom of the hydrocarbons to be produced. A production well extends from the surface to a location proximate the hydrocarbon and a convection passage extends between the energy delivery well and the production well thereby forming a convection loop. The energy delivery well and the production well intersect at a location proximate the hydrocarbon such that the convection loop is in the form of a triangle. Preferably, the convection passage extends upwardly from a point at which the convection passage intersects the production well. The system also includes a heater, such as an electric heater or down-hole burner, disposed in the energy delivery well.

Heater embodiments are presented to aid in the recovery of hydrocarbon from underground deposits. In one embodiment, a heater is provided to a well that has been drilled through an oil-shale deposit. A fuel and an oxidizer are provided to the heater and flue gases are recovered. The heater has a counterflow design and provides a nearly uniform temperature along the heater length. The heater may be designed to operate at different temperatures and depths to pyrolyze or otherwise heat underground hydrocarbon deposits to form a product that is easily recovered and which is useful without substantial further processing. Various embodiments of a counterflow heater are described including heaters having, down the heater length, distributed reaction zones, distributed catalytic oxidation of the fuel, and discrete or continuous heat generation. The heaters may also utilize inert gases from product recovery or from heater flue gases to control the heater temperature.

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.
