ABSTRACT:
A plurality of hydrocarbon fractions are recovered from hydrocarbon-bearing material such as oil shale in a continuous retort wherein a bed of the material is moved through a heating chamber, the heating being for a time and at a temperature effective to strip increasingly heavier hydrocarbon fractions from the material as it moves through the heating chamber. The hydrocarbon fractions are collected by a plurality of collection means disposed along the path of movement of the bed for recovery of a corresponding plurality of hydrocarbon fractions.
