In situ shale-oil recovery process

摘要

Disclosed is a process for converting organic material of oil-shale to predominantly liquids. The oil-shale is first heated to a temperature from about 360 DEG C. to 475 DEG C. in an anionic atmosphere. The resulting liquids and gases are collected and the residue is extracted with a microemulsion capable of extracting organic material from the heat treated oil-shale.
