IPC: C01B32/40
Filed: 2001-07-03
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 cart be transferred back to the combustion chamber and also reused. The combustion chamber is preferably sealed, which combines with the use of relatively pure oxygen to prevent nitrogen and other non-essential gases from inhibiting the combustion/reaction cycle.
