<p>A process for extracting hydrocarbons from solids containing hydrocarbons such as oil shale is disclosed. The process includes supplying (i) crushed hydrocarbon-containing solids, such as oil shale, (ii) a hydrocarbon solvent, and (iii) a hydrogen donor to a reactor, and digesting hydrocarbon-containing solids at an elevated temperature and pressure in the reactor and extracting kerogen from hydrocarbon-containing solids into the hydrocarbon solvent. The process also includes flashing a slurry that forms in the digestion step in a series of stages to a lower temperature and pressure and separating hydrocarbon fractions from the slurry during the course of the flashing step.</p> |
