Gwyn, J E; Roberts, S C

A retorting process for recovery of hydrocarbonaceous fluids from subdivided solid materials, specifically oil shale, is described wherein the subdivided solid material is preheated, retorted, and subjected to heat recovery after retorting, heat transfer being effected by contacting the subdivided solid material as a dilute-phase fluidized bed in a separate preheating zone with a first particulate heat carrier, and with a second particulate heat carrier in a dense fluidized bed in a retorting zone. Separate particulate heat carriers are employed in such manner that one mass of heat carrier is utilized for preheating the solid material and heat recovery, and a second mass of heat carrier is utilized for retorting of the subdivided preheated solid material. 30 claims.
