Abstract:
1. A method of liquefying carbonaceous material in situ to produce liquid hydrocarbon comprising the following steps: (a) applying a first aqueous solution to the carbonaceous material to facilitate an initial liquefaction reaction in a reaction zone in the carbonaceous material that liquefies the carbonaceous material to liquid hydrocarbon and heats the reaction zone to a desired temperature, wherein the first aqueous solution comprises components selected from the group consisting of water, hydrogen peroxide at a (w/w) concentration range between 0.1% to 70%, a solvent at a (w/w) concentration range between 0.1% to 30%, and a first catalyst; and (b) applying a second aqueous solution to the reaction zone in the carbonaceous material once the reaction zone reaches the desired temperature, wherein the second aqueous solution facilitates a continuing liquefaction reaction that liquefies the carbonaceous material to produce liquid hydrocarbon, and wherein the second aqueous solution comprises components selected from the group consisting of water, hydrogen peroxide at a (w/w) concentration range between 0.1% to 70%, a solvent at a (w/w) concentration range between 0.1% to 30%, and a second catalyst, and wherein the second aqueous solution is a fluid selected from the group consisting of a supercritical fluid and a superheated fluid, wherein the fluid is at high pressure prior to being applied to the carbonaceous material and is depressurized to a lower pressure immediately prior to being applied to the carbonaceous material.
