Patent number: 8957265Abstract: Systems and methods for extracting recoverable materials from source materials are provided. Source materials are introduced into a furnace. A condition is created within the furnace in which a gaseous pressure within the furnace is less than an atmospheric pressure outside of the furnace by removing air from within the furnace with a vacuum pump. Hydrocarbons contained within the source material are separated from the source material without using a significant amount of water by heating the source material to a temperature sufficient to cause the hydrocarbons to liquefy or vaporize. The liquefied hydrocarbons or vaporized hydrocarbons are then captured.Type: GrantFiled: May 13, 2014Date of Patent: February 17, 2015Assignee: Green Technology LLCInventors: John Lee Horning, Jan H. Matthias, Nigel Moriarty, John Stuart Lehde

Patent number: 5085764Abstract: In a process for reducing the sulfur and ash contents of coal, coal is sequentially contacted with fused alkali metal caustic, wash water, and acid. Contacting the coal with the caustic produces water-soluble compounds. Sufficient wash water is used to reduce the temperature of the caustic treated coal and dissolve the bulk of the water-soluble compounds before the water-soluble compounds convert to water-insoluble compounds that precipitate on the caustic-treated coal. Caustic removed from the coal by the water is recovered as anhydrous caustic for again contacting coal.Type: GrantFiled: December 19, 1989Date of Patent: February 4, 1992Assignee: TRW Inc.Inventors: Robert A. Meyers, Walter D. Hart, Loren C. McClanathan

Patent number: 4728418Abstract: A novel process for the low-temperature depolymerization and liquefaction of coal wherein the coal is subjected to sequential processing steps for the cleavage of different types of intercluster lnikages during each processing step. A metal chloride catalyst is intercalated in finely crushed coal and the coal is partially depolymerized under mild hydrotreating conditions during the first processing step. In the second processing step the product from the first step is subjected to base-catalyzed depolymerization with an alcoholic solution of an alkali hydroxide, yielding an almost fully depolymerized coal, which is then hydroprocessed with a sulfided cobalt molybdenum catalyst in a third processing step to obtain a hydrocarbon oil as the final product.Type: GrantFiled: October 23, 1985Date of Patent: March 1, 1988Assignee: University of UtahInventors: Joseph S.
