ABSTRACT:
A oil shale retorting process in which oil shale particles are separated into fines and large particles. The large particles are preheated and combined with hot spent shale from a combustor and introduced into a retorting vessel. The fines are introduced into the disengaging section of the retorting vessel. Retort vapors are processed to produce an upgraded syncrude. The portion of the retort vessel where the oil shale and spent shale are introduced has a smaller diameter than the retorting section.
