ABSTRACT:
Crushed oil shale is segregated into a major portion of relatively large particles and a minor portion of "fines" which will pass through screen openings up to about 1/4 inch in size. The large particles are subjected to retorting as an upflowing moving bed in countercurrent contact with downflowing hot eduction gas, while the fines are retorted by controlled distribution over the hot upper surface of the bed of retorted large particles.
