Recovery of hydrocarbon from oil shale involves drying oil shale with superheated steam under specified conditions, continuously heating oil shale to evaporate organic material contained in totally or partly and/or pyrolyzed material

摘要

Recovery of hydrocarbon from oil shale (5) involves drying oil shale with superheated steam (6) by setting temperature of steam at 20-300[deg] C under reduced absolute pressure, continuously heating predried oil shale (5') in a reactor (2) in order to evaporate organic material contained in totally or partly and/or pyrolyzed material. An independent claim is included for plant used for recovery of hydrocarbon from oil shale.
