20110180262 | METHOD OF LIQUEFACTION OF CARBONACEOUS MATERIAL TO LIQUID HYDROCARBON - The present invention provides a method of liquefying a carbonaceous material in situ to produce liquid hydrocarbon comprising applying an aqueous solution to the carbonaceous material to facilitate a liquefaction reaction in a reaction zone in the carbonaceous material that liquefies the carbonaceous material to liquid hydrocarbon, wherein the aqueous solution comprises components selected from the group consisting of water, hydrogen peroxide at a (w/w) concentration range between 0.1% to 70%, methanol at a (w/w) concentration range between 0.1% to 30%, and a catalyst. The aqueous solution may be a superheated fluid, a supercritical fluid, a high-velocity superheated fluid or a high-velocity supercritical fluid. In an embodiment, the reaction zone is heated to a desired temperature by applying a first aqueous solution prior to applying a second aqueous solution that is a super-heated fluid, a supercritical fluid, a high-velocity superheated fluid or a high-velocity supercritical fluid. | 07-28-2011 |
