  • Content Description: An improved process for solvent extraction of organic matter from shale by two extraction steps in sequence. The extraction steps are: (1) treating a kerogen-containing shale with a solvent system comprising a combination of water and an alcohol at a temperature of about 375 to 425/sup 0/C; and (2) treating the product of (1) with a solvent system comprising a combination of an alcohol and another organic solvent at an elevated temperature, but not above about 425/sup 0/C. The organic matter is recovered by separating the liquid which results from step (2) from the shale solids.
