PROCESS FOR EXTRACTING HYDROCARBONS FROM HYDROCARBON BEARING ORES

摘要

PROCESS FOR EXTRACTING HYDROCARBONS FROM HYDROCARBON BEARING ORES Hydrocarbons may be recovered from hydrocarbonbearing ore by reducing the ore to small particles, forming the reduced ore into pellets, setting the pellets, and then contacting the pellets with an extracting solvent. The extracted hydrocarbons usually have an ash content of less than about three weight percent, and the spent pellets usually retain less than 0.75 pounds of solvent per pound of spent pellets.
