摘要： Recovering hydrocarbons from oil shale can include injecting a heated working fluid into a first vessel containing particulate oil shale in a pyrolysis mode. The heated working fluid can have a temperature above a production temperature to pyrolyze kerogen in a stationary bed of the oil shale at or above the production temperature. An effluent can concurrently flow out of the first vessel to be injected into a second vessel in preheating mode. The second vessel containing particulate oil shale has an average temperature below the production temperature so as to capture heat from the effluent sufficient to increase the average temperature of the particulate oil shale and to condense condensable hydrocarbon product while also removing entrained mineral fines mists of condensed hydrocarbons from the effluent. Liquid hydrocarbons can concurrently be collected from the first vessel and/or the second vessel.

摘要： A method of recovering rare earth elements and other trace metals from based ores can include providing a body of rubblized carbon-based ore. The rubblized carbon-based ore can include carbonates and rare earth elements. The carbonates in the ore can be decomposed at an elevated decomposition temperature and an oxygen deficient atmosphere to form an enriched spent ore and carbon dioxide.

摘要： Systems for heating a body of crushed hydrocarbonaceous material to produce hydrocarbons therefrom can involve heating multiple zones of the body of material sequentially. An exemplary system can include a body of crushed hydrocarbonaceous material having a lower zone and an upper zone. A lower heating conduit can be embedded in the lower zone, while an upper heating conduit is embedded in the upper zone. A collection conduit is embedded in the upper zone at a location above the upper heating conduit. A lower heating valve is also operatively associated with the lower heating conduit and is capable of switchably flowing a heat transfer fluid through the lower heating conduit. An upper heating valve is operatively associated with the upper heating conduit and capable of switchably flowing the heat transfer fluid through the upper heating conduit. The lower heating valve and upper heating valve are also configured to sequentially flow the heat transfer fluid through the lower heating conduit and then through the upper heating conduit or through the upper heating conduit and then through the lower heating conduit.

摘要： A method of minimizing vapor transmission from a constructed permeability control infrastructure can comprise forming a heterogeneous hydrated matrix within the constructed permeability control infrastructure, the constructed permeability control infrastructure comprising a permeability control impoundment defining a substantially encapsulated volume. The heterogeneous hydrated matrix includes a particulate solid phase and a continuous liquid phase which is penetrable by a vapor having a permeation rate. The constructed permeability control infrastructure is operated to control the permeation rate by manipulating an operational parameter of the constructed permeability control infrastructure. Additionally, the vapor can be impeded during operating sufficient to contain the vapor within the constructed permeability control infrastructure.

摘要： An articulating conduit linkage system for maintaining a fluid connection between a fluid source and displaceable conduit that has been buried in a subsiding permeable body. A fluid source can supply a working fluid through a source outlet. A displaceable conduit can receive the working fluid through a conduit inlet, and be buried at a depth within a subsiding permeable body that is contained within a permeability control infrastructure. A plurality of articulating conduit segments can include, an outer conduit segment coupled to the source outlet, an inner conduit segment coupled to the conduit inlet, and at least one middle conduit segment coupled to the outer and inner segments. In the event of a subsidence, the plurality of articulating conduit segments are configured so the outer and inner conduit segments extend the conduit linkage system while maintaining a working fluid connection between the source outlet and the conduit inlet.

摘要： Systems for extracting hydrocarbons from a crushed hydrocarbonaceous material can include a body of crushed hydrocarbonaceous material. A pipe can be oriented within the body of crushed hydrocarbonaceous material. The placement of the pipe can be such that the pipe is surrounded on top, bottom, and sides by the crushed hydrocarbonaceous material. The body of crushed hydrocarbonaceous material can be made up of portions having different void fractions. An arching control volume of crushed hydrocarbonaceous material can extend upward from the pipe to a vertical control distance. A support portion of crushed hydrocarbonaceous material can be oriented immediately adjacent sides of the arching control volume. The arching control volume can have a higher void fraction than the support portion. Internal friction between the arching control volume and the support portion can reduce stresses on the pipe as the hydrocarbonaceous material subsides.

摘要： A thermal insulation system can include a body of heated material at an elevated temperature. A layer of porous insulating material can be placed adjacent to and in fluid communication with the body of heated material. The insulating layer can contain distributed liquid water in an amount sufficient to cool the insulating layer through evaporative vapor flow toward the body of heated material. The amount of water can be sufficient to provide water vapor for inhibiting the diffusion and adsorption of hydrocarbons from the heated material. The insulating layer can include a continuous vapor phase. A heat sink material at a lower temperature can be placed adjacent to the insulating layer and opposite from the body of heated material.

摘要： A method of reducing settling of residual comminuted hydrocarbonaceous material during processing can comprise forming a constructed permeability control infrastructure which defines a substantially encapsulated volume; introducing a composite comminuted hydrocarbonaceous material into the control infrastructure to form a permeable body, said composite hydrocarbonaceous material comprising a comminuted hydrocarbonaceous material and a structural material; and heating the permeable body sufficient to remove hydrocarbons therefrom such that the hydrocarbonaceous material is substantially stationary during heating, exclusive of subsidence and settling. The structural material can provide structural integrity to the permeable body sufficient to maintain convective flow of fluids throughout the permeable body during heating.
