In-situ hydrogenation of an underground coal formation is carried out by fracturing the formation and sealing it, to provide an in-situ reactor site. Then a liquid solvent stream and a gaseous hydrogen stream are introduced into the fractured formation, allowing reaction and conversion of the coal to lighter, hydrogenated components.
A process for the recovery of carbonaceous materials from an underground formation, comprising: (a) fracturing a portion of an underground formation, comprising carbonaceous material selected from the group consisting of coal, oil shale, tar sands, and heavy crudes, (b) contacting the carbonaceous
A process for the recovery of carbonaceous materials from an underground formation, comprising: (a) fracturing a portion of an underground formation, comprising carbonaceous material selected from the group consisting of coal, oil shale, tar sands, and heavy crudes, (b) contacting the carbonaceous material in-situ in the fractured formation with (1) a preheated liquid solvent, wherein at least a portion of the liquid is a hydrocarbon-containing liquid having a boiling range of from about 300°F. to about 1200°F., and further wherein at least a portion of the liquid is a hydrocarbonaceous liquid having the property of donating and accepting hydrogen, and having a boiling range of from about 650°F. to about 975°F., and (2) a preheated gas comprising at least 50 volume percent hydrogen, and wherein the pressure in the fractured formation is maintained at from about 200 psi to about 2000 psi, and the temperature is maintained at from about 500°F. to about 900°F., to produce a product mixture of at least a partially hydrogenated carbonaceous material and dissolved carbonaceous material, and (c) removing said product mixture from said formation.
