Environmental impact of in-situ oil shale processing | 2007-10 | in situ processing of oil shale; in situ processing; oil shale; production of oil from kerogen; oil production | The in situ processing of oil shale for the production of oil from the kerogen involves heating the shale slowly to moderate temperatures of between 3000 C and 4000 C. At this temperature, gaseous products that evolve from the oil shale are condensed and recovered. The pathways of creation of oil fr... |
