Apparatus and method for retorting solids
Raw, solid material of an organic-mineral complex is mixed with hot solid material, e.g., spent oil shale, in a rotating kiln which can have baffles oriented to cause the solids to tumble and urge the large particles near its outlet back from the outlet. Hydrocarbon vapors and fine retorted and spent solids pass from the kiln to cyclones which separate fines from vapors. The vapors are drawn off to further processing equipment, while the fines are mixed with oxygen-bearing gas and returned to the retorted solids heater. Hot spent solids from the heater can preheat the incoming oxygen-bearing gas, while exhausted combustion gas from the heater can preheat the solid organic-mineral complex material. (16 claims)
