Mitchell, D S; Sageman, D R

A continuous process is disclosed for the retorting of oil shale or other similar hydrocarbon containing solids. Heat carrier particles at an elevated temperature are introduced into an upper portion of a retort and pass downwardly therethrough, fluidized by an upwardly flowing non-oxidizing gas introduced in a lower portion of the retort. The hydrocarbon-containing solids are introduced into an intermediate portion of the retort; a first portion thereof being entrained by the gas and flowing upwardly through the retort and a second portion thereof being fluidized by the gas and flowing downwardly through said retort. Retorted fluidized solids and heat carrier particles are removed from a lower portion of the retort and a product stream of hydrocarbon vapors mixed with the entrained retorted solids and fluidizing gas is recovered overhead.
