PCT No. PCT/US82/00394 Sec. 371 Date Mar. 10, 1983 Sec. 102(e) Date Mar. 10, 1983 PCT Filed Mar. 30, 1982 PCT Pub. No. WO82/03404 PCT Pub. Date Oct. 14, 1982.A crushed hydrocarbon-bearing material containing hydrocarbon and foreign mineral constituents is dispersed in fused alkali metal caustic to remove the sulfur content and release the foreign mineral matter from the hydrocarbon material for recovery and/or upgrading of the hydrocarbon content. The process permits recovery of 80-95% of the available kerogen or other hydrocarbon in a mineral matrix such as oil shale rock and conditions a solid fossil fuel such as coal, as well as the kerogen or other hydrocarbon released from the mineral matrix, for removal of substantially all remaining ash and other foreign mineral matter by subsequent washing of the hydrocarbon product in an aqueous solution of acid. |
