Abstract
Disclosed is a process for the retorting of shale and other similar hydrocarbon-containing solids in which the solids to be retorted are mixed with a solid heat-transfer material to provide the necessary heat for retorting. The shale is retorted in a spouted bed of the shale and heat-transfer solids. Preferably, molecular oxygen is excluded from the retorting zone.
