Deering, R F

Hot particles removed from a retort, preferably retort-sized particles of oil shale removed from a retort operating at superatmospheric pressure, are crushed and fed to a fluidized surge zone maintained under non-oxidizing conditions at substantially the pressure of the retort to forestall escape of retort gases. Raw fines are introduced into the surge zone and retorted without agglomeration by heat transferred from the hot retorted particles and/or a heated fluidizing gas stream to educe hydrocarbonaceous vapors. Educed vapors are scrubbed, condensed and separated into liquid and gaseous product streams, a portion of the latter being recycled to provide fluidizing process gas streams.
