Abstract: A method of extracting hydrocarbon fuel from oil sand or shale. The oil sand or shale is admixed with a sensitizer and subjected to exposure to microwave energy. This acts to remove the hydrocarbon fuel from the oil sand or shale and can also crack the hydrocarbon, lower sulfur content as well as water content.

Abstract: A method and apparatus for applying microwaves to flowable materials within a centrifuge are disclosed. The simultaneous application of microwaves and centrifugation to flowable materials may be utilized to rapidly separate immiscible components from emulsions and dispersions. Microwaves are guided along a waveguide structure within the centrifuge. A meandering path for the waveguide is chosen through the interior of the centrifuge and through the flowable material being centrifuged. Gradual variation in the radial distance of the waveguide from the axis of the centrifuge produces a gradual filling of the cross-section of the waveguide along its length, forming a gentle microwave beach within the waveguide. Excellent microwave coupling and power deposition into the flowable material results. There is no need to contain the flowable material behind a dielectric barrier, normally placed between the incident microwaves and the flowable material, since confinement is provided by centrifugal forces.

Abstract: A process for producing liquid hydrocarbons from hydrocarbon materials is disclosed. The hydrocarbon materials are heated to a temperature above 400.degree. C. thereby producing a gas stream. A gaseous plasma is generated. The gas stream is passed through the gaseous plasma thereby producing a heated gas stream. The heated gas stream is saturated with a hydroxide ion to produce a saturated gas stream. The saturated gas stream is cooled to standard temperature and pressure and is condensed to produce liquid hydrocarbons and waste gases.

Abstract: The method and associated apparatus for recovering fractions from hydrocarbon material, comprising the steps of generating electromagnetic energy generally in the frequency range of from about 300 megahertz to about 300 gigahertz, in accordance with the lossiness of the material, transmitting the generated electromagnetic energy to the hydrocarbon material, sensing the temperature of the hydrocarbon material, varying the electromagnetic energy in accordance with the sensed temperature, exposing the hydrocarbon material to the electromagnetic energy for a sufficient period of time to sequentially separate the hydrocarbon material into fractions, and removing the resulting fractions.

Abstract: A process for slurry-phase gasification of carbonaceous feedstock materials is provided wherein feedstock materials are combined with a liquid to form a feedstock slurry. Product gases are formed from the feedstock slurry in a gasifier reaction vessel in the presence of elevated temperatures and pressures and ultrasonic energy. Gasification catalysts may be utilized to provide increased reaction rates. The process of the present invention provides enhanced conversion of carbonaceous solids feedstock to gaseous products comprising primarily methane and carbon dioxide with some higher organic liquids.

Abstract: An apparatus and method for extracting hydrocarbons from tar sands. Stationary heater plates have a central opening therethrough through which a horizontal axle extends. Rotors having a central hub and a number of arms are splined on the axle, one closely sandwiched between every two heater plates. A ring is provided between the heater plates closely outward of the rotor arms. Sand retaining pockets are defined between adjacent arms of each rotor, the rotor hub, the ring and adjacent heater plates. Sand is retained in the sand retaining pockets for about one revolution about the axis between feed and removal positions. While retained in the pockets, the sand is heated and hydrocarbons driven off are collected.

Abstract: A new technology for the extraction of liquid hydrocarbon products from fossil fuel resources such as oil shales, tar sands, heavy oils and coals which comprises the mixing of a donor solvent with the fossil fuel and the exposure of the mixture to ionizing radiation. The donor solvent supplies hydrogen for combination with molecules whose bonds are broken by the irradiation process. The method may be conducted at or above ambient temperatures and pressures.
