    摘要: A method for producing a kerogen concentrate from oil shale comprises treating shale with an aqueous caustic treating solution to produce a shale product of substantially transformed mineral content, and then treating the shale product with an aqueous acid solution to produce a kerogen concentrate. The acid solution extracts minerals from the shale product to lower the ash content of the kerogen concentrate. A spent acid solution containing the extracted minerals can be treated to recover minerals therefrom.

    摘要: A method for producing a kerogen concentrate from oil shale comprises treating shale with a first aqueous caustic treating solution to produce a shale product of substantially transformed mineral content, and then treating the shale product with an aqueous acid solution to produce a first kerogen concentrate. The acid solution extracts minerals from the shale product to make a low ash content first kerogen concentrate. A spent acid solution containing the extracted minerals can be treated to recover minerals therefrom. The first kerogen concentrate is then treated with a second aqueous caustic treating solution to produce a second kerogen concentrate of lower ash content. The first and second aqueous caustic treating solutions are preferably the same.

    摘要: Disclosed is a method for detecting the flame front during the in situ combustion of a subterranean carbonaceous stratum which involves providing one or more radio transmitters below the surface of the ground, each of said transmitters being capable of sensing and transmitting information concerning the physical and chemical properties of its surroundings, and monitoring said transmissions as an indication of the extent and movement of said flame front. Also disclosed is a method for detecting non-uniform packing characteristics of rubblized material which involves providing one or more radio transmitters within the boundaries of a retort capable of sensing and transmitting information concerning the physical parameters of its surroundings, and monitoring said transmissions as an indication of the size and density distributions of the rubble in said retort.
