Vasalos, I

A fluid bed process and system is disclosed for retorting hydrocarbon-containing material, such as oil shale, coal and tar sand, in which hydrocarbon-containing material and heat carrier material are fed into a mixing chamber, mixed and rapidly transported upwardly by a lift gas through a lift pipe into a solids-containing vessel to retort the hydrocarbon-containing material with minimal thermal cracking of the liberated hydrocarbons to increase the recovery of condensable hydrocarbons. The retorted material can be conveyed to a dilute phase lift pipe and combustor vessel where carbon residue in the retorted material is combusted leaving hot spent material that can be fed into the mixing chamber as heat carrier material.
