20080202985 | Method for recovery of hydrocarbon oils from oil shale and other carbonaceous solids - A continuous, efficient surface method for thermal recovery of hydrocarbons from a solid feedstock is described that includes a self-contained process that produces hydrogen for upgrading the hydrocarbons to produce motor fuel. The hydrogen also is used as a clean burning fuel for the thermal processing. The hydrogen is produced as a component of synthesis gas formed by gasification of coal. The synthesis gas is processed to remove and dispose of carbon dioxide and by-product sulfur. Combustion of the hydrogen to provide indirect heating of the solid feedstock maximizes hydrocarbons that can be upgraded and reduces or eliminates the emission of carbon dioxide into the atmosphere. | 08-28-2008 |
