  • Patent number: 8002972
    Abstract: A system for producing petroleum products from oil shale includes one or plural kiln lines made up of plural series-connected, indirect-fired, inclined rotary kilns. Plural kiln lines are operated for parallel processing. Oil shale is advanced through kilns in succession and exhausted from each kiln line substantially free of hydrocarbons. Successive kilns along the advancement of oil shale are maintained at successively higher temperatures. A fuel distinct from hydrocarbons in oil shale, such as syngas from a gasifier or hydrogen gas from a separator, drives pyrolysis to extract hydrocarbons. A refining unit located proximate to the kiln lines upgrades extracted hydrocarbons into petroleum products and separates the petroleum products by criteria. A heat extraction unit recovers heat from exhausted oil shale for reuse in kilns. A method involves drying oil shale followed by heating dry oil shale in successively hotter pyrolysis environments.

  • Patent number: 7807049
    Abstract: The present invention relates to a method and apparatus for extracting kerogen oil from oil shale without adverse environmental impacts. A first plasma reactor is employed for creating a syngas from a carbon-based fuel. A turbine uses the syngas to produce electricity after the syngas' sensible heat passes through a heat exchanger to heat recycling gases used to pyrolyze the oil shale. A kiln receives the oil shale and heats the oil shale to a temperature at which hydrocarbons from the oil shale are released and captured. The hydrocarbons are sent to a distillation tower to produce a usable fuel. A second plasma reactor vitrifies the spent shale to produce an environmentally inert byproduct. The second plasma reactor is powered by electricity produced by the syngas turbine. Carbon dioxide generated by the process is captured and stored to prevent its release into the environment.

    Abstract: Process and apparatus for extraction of oil and hydrocarbons from crushed hydrocarbonaceous solids, such as oil shale, involving the pyrolyzing of the crushed solids with liquid hydrocarbon and syn gas rich in hydrogen and carbon dioxide. Crushed hydrocarbonaceous solids are treated with liquid hydrocarbon and hot syn gas at an elevated temperature in a rotary kiln where the crushed solids are cascaded into the hot syn gas for sufficient time to strip the volatile liquids and gases found in the solids, removing the vaporized liquids, enriched syn gas and spent crushed solids from the kiln, fractionating the vaporized liquids and enriched syn gas into the desired fractions. The enriched syn gas is particularly suited for use in combined-cycle electricity generation and in the preparation of various by-products. The process efficiently recycles heat and energy to reduce harmful atmospheric emissions and reliance on external energy sources.

  • Patent number: 6464860
    Abstract: A process and apparatus for extracting oil from oil shale. Crushed oil shale is transported into a combustion chamber, along with relatively pure oxygen and carbon monoxide which are combusted to heat the oil shale sufficiently to release petroleum hydrocarbons, leaving a retorted oil shale containing a carbon residue. The combustion phase combines with the carbon residue to generate a recurring combustion/reaction cycle in which the carbon monoxide and oxygen are combusted to form carbon dioxide while retorting the oil shale by heat, and the carbon dioxide reacts with the carbon residue in the retorted oil shale to regenerate a carbon monoxide by-product. The petroleum hydrocarbons are cooled and processed into useable oils. The carbon monoxide by-product can be re-routed back to the combustion area of the combustion chamber and reused, or used in some separate application. Heat from the released petroleum and carbon monoxide by-product can be transferred back to the combustion chamber and also reused.

  • Patent number: 6110359
    Abstract: A method for extracting bitumen from crushed mined tar sands comprising contacting the mined tar sands with a solvent in the presence of sonic energy in the frequency range of 0.5 to 2.0 kHz. Specifically, a solvent is first mixed with crushed mined tar sands and the mixture is then formed into a slurry of tar sand suspended in the solvent. Thereafter the tar sand slurry is injected into the top of a vertically disposed, substantially rectangular shaped, hollow acoustic chamber of uniform cross-section. Fresh solvent is injected into the bottom of the acoustic chamber and flows upwardly through the cell. The fresh solvent is injected into the bottom of the acoustic chamber at a rate low enough whereby the tar sand particles in the slurry fall by gravity through the upwardly flowing solvent. The tar sand particles and solvent in the acoustic chamber are subjected to acoustic energy in the frequency range of 0.5 to 2.

  • Patent number: 6060631
    Abstract: A process for the conversion of plastic to produce a synthetic crude oil by means of separating a liquefied plastic into a lower boiling fraction and a higher boiling fraction containing non-distillable particulate matter which is admixed with a hydrocarbonaceous recycle stream and filtered. The filtered stream having a reduced concentration of finely divided particulate matter and the distillable lower boiling stream together with hydrogen is contacted with a hydro-demetallization catalyst in a hydro-demetallization zone. The effluent from the hydro-demetallization zone is contacted with a hydrocracking catalyst in a hydrocracking zone to produce lower boiling hydrocarbons suitable for use as a synthetic crude oil and to produce gaseous, water-soluble inorganic compounds. A recovered hydrogen-rich gaseous stream is preferably recycled to the hydro-demetallization zone. The gaseous, water-soluble inorganic compounds are removed by scrubbing the hydrocracking zone effluent with an aqueous stream.

  • Patent number: 6007699
    Abstract: A process for oxidizing fuel and transferring the heat produced to a particular use in a combustion system such as fuels conversion. A bed of a mixture of materials forming an unmixed combustion catalyst, which in an oxidized state is readily reducible and in a reduced state is readily oxidizable, is placed in efficient thermal contact with a heat receiver for use in the combustion system. Fuel and air are alternately contacted with the bed, whereby the fuel is oxidized, the air is depleted of oxygen, and heat is liberated. The heat is efficiently transferred to the heat receiver by careful selection of the materials of the bed such that the temperatures produced when the fuel is oxidized and when the air is depleted of oxygen are advantageous to the particular use in the combustion system.

  • Patent number: 5964985
    Abstract: A method of forming liquid hydrocarbons from solid coal. The coal is pulverized to provide a particulate coal feed, which is then extruded to provide a hollow tube of compressed coal supported inside of a support tube. A clay feed is extruded to provide a hollow tube of compressed clay supported inside of the coal tube and a combustible fuel is burned inside of the clay tube. The temperature of combustion is sufficient to fire the extruded clay and pyrolyze the extruded coal to produce hydrocarbon gases and coal char. The support tube has holes for releasing the hydrocarbon gases, which contain suspended particles formed during combustion. The suspended particles are removed from the hydrocarbon gases to provide clean gases, which are passed through an ionizing chamber to ionize at least a portion thereof. The ionized gases are then passed through a magnetic field to separate them from each other according to their molecular weight.
