摘要：Method and apparatus for treating a mixture of mineral substrate particles andhydrocarbon compounds, especially tar sands and contaminated soils, to recover a
hydrocarbon portion and a cleaned substrate portion. Hydrocarbonaceous rock, sand,ore, or soil containing bitumen, petroleum, and/or kerogen is crushed or otherwisecomminuted as needed to the particle size of sand or smaller. The comminuted ore ismixed with water to form a slurry, is heated to between 60° C. and 100° C., and is blendedwith an oxidant in aqueous solution, preferably hydrogen peroxide. Both free interstitialhydrocarbons and those hydrocarbons bound electrostatically to the surfaces of clay-like particles in the ore are released from the mineral substrate. Some of the releasedhydrocarbon compounds may be controllably cleaved by the oxidant to yield organiccompounds having lower average molecular weights which are suitable for refining as oilafter separation from the process water phase and the residual particulate mineralsubstrate. The water and mineral tailings from the process are substantially free ofhydrocarbon contamination and are environmentally suitable for disposal remediation.
